Aluminum From Soda Cans Lab

The objective of this lab was to use prior knowledge about the Law of Conservation of Matter and of different types of chemical reactions in order to evaluate if aluminum disappears during the reaction and copper appears. The reaction that occurred between Copper (II) Chloride and aluminum was a single replacement reaction. Clear signs that a chemical reaction took place include heat release/temperature change, color change, and formation of a precipitate. When a single element, in this instance aluminum, replaces another element in a compound, copper, a single replacement reaction occurs. A basic formula for these reactions is AB + C → AC + B.

Experiment 55 consists of devising a separation and purification scheme for a three component mixture. The overall objective is to isolate in pure form two of the three compounds. This was done using extraction, solubility, crystallization and vacuum filtration. The experiment was carried out two times, both of which were successful.

First students obtained 8 graduated cylinders and labeled them. Each one contained a different ratio of vinegar and water. These graduated cylinders with the liquid were weighed and recorded.Then, students obtained an Alka-Seltzer tablet and recorded its mass. Then one alka-seltzer tablet was dropped into each of the graduated cylinders. Students had to

Purpose: The purpose of this experiment is to observe a variety of chemical reactions and to identify patterns in the conversion of reactants into products.

For this lab, we brought a empty soda can to school to show how pressure and temperature can affect the structure of the can. To begin the experiment, we needed a empty soda can, water and ice in a small plastic tub, and a hot plate. First, we added about a tablespoon of water to the empty soda can. Second, we put the soda can on the hot plate and waited until the water was brought to a boil. Then we used beaker tongs to carry the hot soda can and flipped it over into the container of water and ice. Once the can touched the water, the can made a loud crushing sound and the can crippled inward.

Experiment 3: Identification of an Unknown Mixture by Extraction, Recrystallization, and Melting Point Determination Abstract In this experiment, an unknown compound was identified using extraction and recrystallization techniques. This was followed by a determination of the melting points of the extracted and recrystallized substances. Each unknown compound consisted of two substances that were either a carboxylic acid, a phenol or a neutral.

Campbell’s Soup Cans presents thirty-two duplicate paintings of different flavored Campbell soup cans. All of the paintings were painted on white canvas and displayed in rows as if, “resting on a shelf like groceries in a store” (MoMA). Each piece is nearly identical to the first with the main difference being that each name of the soup’s flavor is different, two specific soup cans with a ribbon across the seal stating, “NEW, GREAT AS A SAUCE, TOO”, and another with the words “Old-fashioned” above the flavor label. Each can has a black outlines and details, red upper half, brown centered seal, while lower half, read flavor name, black and gold “SOUP”, gold printed patterns, and a single red line. The MoMA states, “Warhole assigned a different

In this lab students tested the given contaminated (hard water) for the ions present in the water prior to the distillation, and then after the distillate (pure water) was collected, the same procedures were followed to prove the absence of the hard water contaminates. SPAN Chemistry is so called because this dual-credit class spans the gap between high school and the extremely rigorous college chemistry expectations.

These experiments demonstrated ways to discover more efficient ways to filter and purify water in the future. With experiment #1 vinegar was filtered through dirt and came out fairly clean. On experiment #2 water came out clean through filtration and on experiment #3 after using the test strips on the water samples, I discovered that Dasani and Fiji water have a lot of similarities. One of them being healthier for drinking

The experiment was a success because all of the ultimate goals were completed. The volume of CO2 released from the pop rock reaction was calculated and found at 58 mL. The moles of CO2 was calculated at .00233 mol. The experiment was also a success because it was found that the heat released from combining and eating pop rocks with soda would not kill the consumer unless it was consumed in very high doses. The combination is not dangerous because it doesn't release a large amount of heat. The simulation of stomach acid, pop rocks, and soda reviled that the temperature increase during the reaction is minimal. Some possible errors of this experiment was missing some of the CO2 when the tube escapes the graduated cylinder. To avoid this in the future the tube could be held during the apparatus processes. Another possible error is miscalculation of LD50. In the future calculations could be done more precisely and

Everyone has done the volcano science project and I loved making bottles explode with a little baking soda and vinegar, but I wanted more. I spent (and still do) hours watching interesting science experiments ranging from the Pharaoh’s Serpent to precious metal refinery. However, most of the experiments were out of the reach of a young chemist at home. Instead, I looked around for chemical experiments going on around me.

Distillation is a method of separating two volatile chemicals on the basis of their differing boiling points. During this lab, students were given 30 mL of an unknown solution containing two colorless chemicals. Because the chemicals may have had a relatively close boiling point, we had to employ a fractional distillation over a simple distillation. By adding a fractionating column between the boiling flask and the condenser, we were able to separate the liquids more efficiently due to the fact that more volatile liquids tend to push towards the top of the fractionating column, thereby leaving the liquid with the lower boiling point towards the bottom. After obtaining the distillates, we utilized a gas chromatograph in order to analyze the volatile substances in the gas phase and determine their composition percentage of the initial solution. Overall, through this lab we were able to enhance our knowledge on the practical utilization of chemical theories, and thus also demonstrated technical fluency involving the equipment.

In the present experiment, I will be exploring the potential for utilizing desalination to increase the quantity of potable water for human consumption. Water is a

The soda ash form experiment 3 was obtained. A 250 ml beaker was obtained and rinsed.
