Red, White and Blue Electrolysis Chemistry Demonstration

Here is a perfect electrochemistry chem demo for the 4th of July or other patriotic holiday. Use salt bridges to connect three beakers of liquids (clear, red, clear). Apply a voltage and watch the solutions turn red, white and blue.

Place a carbon electrode in each beaker.Wrap one end of the copper wire around one the carbon electrodes at the end of the row. Slip rubber tubing over the copper wire to cover the exposed wire that will be between the electrodes. Wrap the other end of the copper wire around the third carbon electrode, at the end of the row of beakers. Skip the center carbon rod and be sure no exposed copper touches it.Fill the two U-tubes with 1M KNO3 solution. Plug the ends of each tube with cotton balls. Invert one of the U-tubes and hang it over the rim of the left and center beaker. The arms of the U-tube should be immersed in the liquid. Repeat the procedure with the second U-tube and the center and right beakers. There should not be an air bubble in either U-tube. If there is, remove the tube and re-fill it with KNO3 solution.Place a glass stirring rod in each beaker.Make certain the power supply is off and t hen connect the positive () terminal to the central carbon electrode and the negative (-) terminal to one of the outer carbon electrodes.Add 1 mL of thymolphthalein solution to the beaker on the right and 1 mL of phenolphthalein indicator to each of the other two beakers.Add 1 mL of 0.1M NaOH solution to the middle beaker. Stir the contents of each beaker. From left to right, the solutions should be: clear, red, clear.These solutions may be stored in sealed containers and may be re-used to repeat the demonstration. If the colors become faint, more indicator solution may be added. Perform the Demonstration Turn on the power supply. Adjust it to 10 volts.Wait 15 minutes. Turn off the power supply and stir each solution.At this point, the solutions should now appear red, colorless and blue. You may wish to place a white sheet of paper or posterboard behind the beakers to display the colors. Also, this makes the center beaker appear white.You can return the solutions to their original colors by reversing the connections to the power supply adjusting it to 10 volts, and allowing 20 minutes before turning off the power and stirring the solutions.Another way to return the solutions to their original colors is to add 0.1 M H2SO4 to the beakers on the end until the liquids turn colorless. Add 0.1 M NaOH to the middle beaker until the liquid turns from clear to red. Disposal When the demonstration is complete, the solutions may be rinsed down the drain with water. How It Works The chemical reaction in this demonstration is simple electrolysis of water: The color change is a result of the pH shift accompanying electrolysis acting on the pH indicators, which were selected to produce the desired colors. The anode is located in the center beaker, where water is oxidized to produce oxygen gas. Hydrogen ions are produced, decreasing the pH. 2 H2O(l) → O2(g) 4 H(aq) 4 e- Cathodes are located on either side of the anode. In these beakers, water is reduced to form hydrogen gas: 4 H2O(l) 4 e- → 2 H2(g) 4 OH-(aq) The reaction produces hydroxide ions, which increase the pH.

Think and Grow Rich by Napoleon Hill - 1047 Words

Executive Summary: â€Å"Think and Grow Rich,† by Napoleon Hill In the book â€Å"Think and Grow Rich,† the author, Napoleon Hill, provides a set of principles that he calls the key to financial success. The idea at the center of these principles is that one becomes what he or she frequently thinks about, in this case success (i.e. rich). Hill lays out a method he created to translate one’s thoughts into reality, creating an insatiable hunger and drive within an individual to succeed. Using the examples of his son and some of America’s legendary iconic business leaders, of which Hill studied and interviewed, including Edwin C. Barnes, he demonstrates that anything one puts his or her mind to can be produced and conceived. â€Å"†¦[All] who have†¦show more content†¦Using his son as another example, Hill shows that even what may seem impossible is attainable and did not let any negative stand in the way of his goal. His son was born with no p hysical ears, even though the doctor said the contrary, Hill did not want accept the fact that his son was deaf. Hill was determined that his son would hear and speak, and wanted to implant in his son the same burning desire at an early age. Every day, Hill repeatedly told himself that he would not accept his son as a deaf mute. Even though his son had a slight capacity to hear, Hill knew that he could develop a greater hearing capacity. Using what his father taught him, at a young age, he used his affliction to his advantage to earn money selling newspapers. He was able to receive extra money from people because of he was handicapped. As he grew older, his son applied the same principles to his lifelong desire to hear, which became reality after going through trial and error of hearing devices, finally stumbling upon one that worked. Both Hill and his son stayed optimistic and did not accept defeat. Through constant thought of wanting to succeed, even with afflictions that were la ter turned into assets, was how which the goal of hearing, speaking and ultimate being rich were obtained.

Thoughts on Love Dating and Marriage Free Essays

There are many different thoughts about dating, love and marriage. I had the pleasure of interviewing six co-workers from different lifestyle regarding their views on these matters. I will compare their thoughts with the theories of love and attachment. We will write a custom essay sample on Thoughts on Love Dating and Marriage or any similar topic only for you Order Now The social science theories that help us understand the components and processes of love include attachment theory, Reiss’s wheel theory of love, Sternberg’s triangular theory of love, Lee’s research on the styles of loving, and exchange theories. Many people perceive marriage as an important occasion in their lives, while others take marriage for granted and not that serious. Do people just hate each other after a while? What happens when the vows are in place, do people get too relax into their real selves? Or is it just unrealistic today? Dan a Gay Caucasian 43 yr. old male feels that marriage is fading away. He doesn’t know if people understand what they are entering into, rather it is love or lust. Dan feels that these idealistic dreams often sweep people off of their feet and then in a few years or less – Reality Hits – Ouch! Marriage is no longer a bringing together of a family, business or wealth. † It is actually based on this strange concept called love and with the concept of family to some people. Families are not the stable, strong and the dominant group that is shaping the young. â€Å"Families are unstable and weak however bonds are weaker. † As far as Gay marriages goes Dan fee ls that it should be legal and that it should not be called or treated and different than a marriage. Even though the church doesn’t rule the populace anymore Dan feels that marriage should be a legal coupling and not a religious coupling. Then he yelled â€Å"WHY DON’T PEOPLE STOP SAYING MARRIAGE IS SOME SACRED INSTITUTION THAT CANNOT BE DARKENED BY THE EVIL GAYS. WITH THE DIVORCE RATE THAT WE HAVE, the agreement that marriage is some sacred institution just rings hollow. Dan feels that an arranged marriage seems to last longer than marriage of choice and that people seem to grow to love each other that are put together by religion or family. However he will never support the mandating of an arranged marriage. Dan was heartbroken over premarital sex due to people not being responsible and protecting themselves. It saddened him to think about the many unwanted babies and the quantity of single mothers that we have in the economy today. These children and mothers are really being robbed of the American Dream. Dan believes that some people can find love on the internet the same way that his mom found her soul mate there. He believes that everyone should be happy. Next I interviewed three Caucasian women, Marcie a29yr old woman divorced once and remarried again with one child by the second marriage. Nikki, divorce twice and she is single mother of two with one child that diagnosed as being autistic. Then there is Kaitlyn a 22yr old white bisexual lady. Even though these women came from different beliefs and lifestyles their opinions on these issues were pretty much the same. They believe that choosing a lover, a husband and a partner is based on one’s personality and the way that they were raised. All three believes that people should live together before getting married. Nikki and Marcie do not believe in open marriages and feels that an open marriage allows each other to cheat and be with someone else. Kaitlyn on the other hand feel that an individual can love more than one person. She is all for open marriages. It’s funny, but all three women have found their recent husband or lover on the internet. They seem to be happy and would recommend internet dating to their friends. Marcie and Kaitlyn believe in premarital sex while Nikki is still deep-rooted by some of her family beliefs which are not to have sex until married. As you can see love is beyond constraints in these women lives. Last but not least there is Craig and Shon. Craig is a 52yr old Caucasian male and Shon is a 40year old African American. Both men were married and are now divorce with children in their twenties. Soon these men will be moving in with their girlfriend of three years. Even though open marriages are not for them, Craig believes in â€Å"What floats your boat. † While Shon showed a little jealously about the situation. He feels that people should not play with emotions because when he is with someone he is with that person. In these men lives, they believe that marriage is the act of a physical union. They have free choice over arranged marriages even if cultural differences play a role in certain marriages. They support two people who have a bond to be able to have their marriage recognized by the state and church. In their eyes Gay marriages is a civil rights movement and have no complaints about a person who wants to stay single. It’s your choice and whatever floats your boat. Just live life and be happy. Even though I have not talked about the theories one on one in this report one can see that all theories applied to every person that was interviewed. However I will explain each theory the way that our text clarified it. Attachment theory proposes that our primary motivation in life is to be connected with other people because this is the only true security we will ever have. The Attachment theory comes in three different styles. * Secure style: I find it easy to get close to others and am comfortable depending on them and having them depends on me. I don’t often worry about being abandoned or about someone get-ting too close to me. * Avoidant style: I am somewhat uncomfortable being close to others; I find it difficult to trust them completely and to depend on them. I am nervous when anyone gets too close and when lovers want me to be more intimate than I feel comfortable being. Anxious/ ambivalent style: Others are reluctant to get as close as I would like. I often worry that my partner doesn’t really love me or won’t want to stay with me. I want to merge completely with another person, and this desire sometimes scares people away. Sternberg’s Triangular Theory of Love According to Sternberg, the mix of intimacy, passion, and commitment can vary from one relation-ship to another. Relationships thus range from nonlove, in which all three components are absent, to consummate love, in which all the elements are present. Intimacy encompasses feelings of closeness, connectedness, and bonding. * Passion leads to romance, physical attraction, and sexual consummation. * Decision/ commitment have a short- and a long-term dimension. In the short term, partners make a decision to love each other; in the long term, they make a commitment to maintain that love over time. Lee’s Styles of Loving According to Lee, there are six basic styles of loving: Eros, mania, ludus, storge, agape, and pragma, all of which overlap and may vary in intensity * Eros means love of beauty. Because it is also characterized by powerful physical attraction, eros epitomizes â€Å"love at first sight. † This is the kind of love, often described in romance novels, in which the lovers experience palpitations, light-headedness, and intense emotional desire. Erotic lovers want to know everything about each other— what she or he dreamed about last night and what happened on the way to work today. They often like to wear matching T- shirts and matching colors, to order the same foods when dining out, and to be identified with each other as totally as possible. MANIA Characterized by obsessiveness, jealousy, possessiveness, and intense dependency, mania may be expressed as anxiety, sleeplessness, and loss of appetite, headaches, and even suicide because of real or imagined rejection by the desired person. Manic lovers are consumed by thoughts of their beloved and have an insatiable need for attention and signs of affection. Mania is often associated with low self- es teem and a poor self- concept. As a result, manic people typically are not attractive to individuals who have a strong self- concept and high self- esteem. LUDUS is carefree and casual love that is considered â€Å"fun and games. † Ludic lovers often have several partners at one time and are not possessive or jealous, primarily because they don’t want their lovers to become dependent on them. Ludic lovers have sex for fun, not emotional rapport. In their sexual encounters, they are typically self- centered and may be exploitative because they do not want commitment, which they consider â€Å"scary. † * STORGE is a slow-burning, peaceful, and affectionate love that comes with the passage of time and the enjoyment of shared activities. Storgic relationships lack the ecstatic highs and lows that characterize some other styles. Sociologist Ira Reiss and his associates proposed a â€Å"wheel theory† of love that generated much research for several decades. Reiss described four stages of love: rapport, self- revelation, mutual dependency, and personality need fulfillment. In the first stage, partners establish rapport based on cultural backgrounds with similar upbringing, social class, religion, and educational level. Without this rapport, according to Reiss, would- be lovers do not have enough in common to establish an initial interest. In the second stage, self- revelation brings the couple closer together. Because each person feels more at ease in the relationship, she or he is more likely to discuss hopes, desires, fears, and ambitions and to engage in sexual activities. In the third stage, as the couple becomes more intimate, the partners’ mutual dependency in-creases: They exchange ideas, jokes, and sexual desires. In the fourth and final stage, the couple experiences personality need fulfillment. The partners confide in each other, make mutual decisions, support each other’s ambitions, and bolster each other’s self- confidence. Like spokes on a wheel, these stages can turn many times that is, they can be repeated. For example, partners build some rapport, and then reveal bits of them, then build more rapport, then begin to exchange ideas, and so on. The spokes may keep turning to produce a deep and lasting relationship. Or, during a fleeting romance, the wheel may stop after a few turns.

Liberal Education vs Technology Essay Example For Students

Liberal Education vs Technology Essay Education is one of the most important tools that a society can possess. The right implementation of this tool is one of the greatest ways of assuring the quality of life within a society. Our society will suffer significantly, with the loss of arts and humanities in our educational system, because we will loose many valuable aspects of our society. Our society will be technology driven, which will in turn lead to no social interaction, traditional culture will be lost, and millions will be without jobs. Traditional liberal arts (often defined effectively just as the humanities, arts and perhaps social sciences) remain the preferred course of study best suited for preparing individuals for rich and successful personal lives. Personal responsibility, accountability, and integrity are essential virtues, required for a civil society to function. As such, they are key components of a liberal education. Not having Liberal education in our educational system will be a great loss. This world is going to be nothing more than a technology driven world, which will lead to absolutely no social interaction at all. Already gearing toward this, one of the Presidents, top 10 goals for the educational system, is to have every classroom connected to the Internet and to have each student technologically literate by the year 2001. This will soon lead to everyone communicating through the computer by e-mail, and chat rooms, thus loosing all face-to-face interactions. We can already see this starting to happen in todays society. I know that Im a victim of it, while at work, I chat with my friends over the new chat messengers, because it is easier to type how you are feeling then to say it, plus you can chat while you are doing other things, like working. If everyone is like me and would rather have convenience they will start using this as their way of communicating as well. At least I know what it will outcome will be and I think the world will be a huge devastation without social interaction. Without social interaction, people would not know how to communicate with each other and social traits would be lost. There is no better medicine for the disease of cultural bias and ethnocentricity than interaction with others. The lack of physical interaction, which would be associated with a virtual education, might have some unforeseen negative effects on the student. Students as well as people will have no problem solving skills, people skills and communication problems because computers will now do it for us. Liberal education teaches students how to broaden their minds and expand their engagement with society. Without it, we will have no personal development nor will we have any successful contributions to society. Without liberal education, people will have no sense of culture nor will they understand any other cultures and maybe not even their own. According to Leo Strauss, Liberal education is education in culture or toward culture. Culture shapes our experience by providing us with a way of understanding the world. With lack of culture, people will not go to different parts of the world to explore or enjoy. People will not even think twice about their heritage or background of their family members either because they are too involved in technology or simply because they dont care. Children might only hear stories or tales from elders about their culture, but the majority of us will be left in ignorance. Culture is an integral part of ones behavior, without it who knows what forms of behavior one will possess. Understanding culture helps us understanding how the physical world around us functions, without it we will be lost. .u663b4f6432e38fef08d80c127df9d28d , .u663b4f6432e38fef08d80c127df9d28d .postImageUrl , .u663b4f6432e38fef08d80c127df9d28d .centered-text-area { min-height: 80px; position: relative; } .u663b4f6432e38fef08d80c127df9d28d , .u663b4f6432e38fef08d80c127df9d28d:hover , .u663b4f6432e38fef08d80c127df9d28d:visited , .u663b4f6432e38fef08d80c127df9d28d:active { border:0!important; } .u663b4f6432e38fef08d80c127df9d28d .clearfix:after { content: ""; display: table; clear: both; } .u663b4f6432e38fef08d80c127df9d28d { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u663b4f6432e38fef08d80c127df9d28d:active , .u663b4f6432e38fef08d80c127df9d28d:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u663b4f6432e38fef08d80c127df9d28d .centered-text-area { width: 100%; position: relative ; } .u663b4f6432e38fef08d80c127df9d28d .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u663b4f6432e38fef08d80c127df9d28d .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u663b4f6432e38fef08d80c127df9d28d .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u663b4f6432e38fef08d80c127df9d28d:hover .ctaButton { background-color: #34495E!important; } .u663b4f6432e38fef08d80c127df9d28d .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u663b4f6432e38fef08d80c127df9d28d .u663b4f6432e38fef08d80c127df9d28d-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u663b4f6432e38fef08d80c127df9d28d:after { content: ""; display: block; clear: both; } READ: Photograph Analysis Essay Example Andy Warhol Employers already report that too many students are leaving our educational system unprepared for working with different cultures within their environment.
