Copper/ Red Stuff/ Chemical Reaction
The purpose of this experiment was to determine what the red stuff that was produced was. We put aluminum foil in a test tube filled with 100 milliliters of copper chloride. During the experiment, I observed that the aluminum foil was breaking away, the aluminum foil that was breaking away was turning into red stuff. After a while, the once light blue copper chloride was turning into a dull gray, almost clear. As the experiment went on, and as the blue copper chloride was turning clear, the reaction of the aluminum foil was slowing. The lighter the copper chloride got, the slower the red stuff was being produced. The purpose of this experiment was to determine what that red stuff was, aluminum or copper. The red stuff that was produced eventually dried out overnight and when I came back next class, it was completely dry. When it is dry, it is really fragile, it breaks to the touch and it stains anything it breaks apart on. It was a orangish brown color when it is dry, but when it is wet, it is a dark maroonish color. Compared to how much aluminum foil we put into the graduated cylinder, there was a very little amount of red stuff that was produced. So far, I’ve determined that the red stuff is copper, but I don’t know …show more content…

Gather materials (beaker, 100 milliliters of copper chloride, graduated cylinder, funnel, 2 centimeter by 15 centimeter aluminum foil strip, goggles, gloves, apron, hydrochloric acid, and a spoon to push down the aluminum foil so that it doesn’t rise up and drip copper chloride down the side)
2. Pour 100 milliliters of copper chloride into the graduated cylinder to measure it
3. Pour the copper chloride into the beaker or leave it in the graduated cylinder (whichever you want to conduct the experiment in)
4. Fold the tin foil in half the long way so that you have 1 centimeter by 15 centimeter strip of aluminum foil
5. Curl it into a coil/spring
6. Place the aluminum foil strip into the copper

Next, a 10 mL beaker is filled with 3 mL of HCl and measure 10 mL of ionized water into a 140 mL beaker. Carefully turn on laboratory burner and start cleaning the Nichrome wire by dipping it into concentrated HCl acid. Hold the Nichrome wire on top of the flame and repeat the step until the wire doesn 't show any color. When the wire is clean, dip the wire again with some of the acid and dip it into the solution with the unknown compound in it. Place the wire back into the flame again and observe the color of the flame.

With background knowledge of chemistry, it is known that aluminum also has a molecular weight of 26.981 g/mol, which then lead to the reaction of 0.0374mol of aluminum. The first reactant was a redox reaction, formed through aluminum, adding potassium hydroxide and water to yield potassium aluminum hydroxide, plus hydrogen. During the process of this reaction, there was many changes occurring. The color of the reaction turned grey at first then eventually turned black. The solution was also evaporating due to the use of the fume solution.

each paper remained it's original color, thus concluding that the unknown was neutral. These results also led the students to believe the unknown was CaCl2 since it was listed in the neutral column. After the litmus test was conducted the students added a few drops of Na3PO4 to the unknown. When these two were combined a precipitate was formed. This final test on unknown F verified that it was CaCl2.

When we placed the aluminum foil in copper chloride, a chemical reaction occurred. Before the reaction took place we had aluminum foil and copper chloride as our reactants. After the reaction happened, the products were aluminum chloride and copper. After the foil was placed in the copper chloride, the color of the aluminum foil had changed from a shiny silver, to a deep red. Also, the color of the copper chloride changed from a light blue to a murky green.

Throughout the experiment, copper was altered a total of 5 times, but after the final chemical reaction, solid, elemental copper returned. Each time the solution changed color, a precipitate formed, or when gas appeared, indicated that a chemical reaction was occurring. For the first reaction, copper was added to nitric acid, forming the aqueous copper (II) nitrate (where the copper went), along with liquid water, and

As the water was added to the heated sample, the solid copper chloride began to dissolve into a pretty blue-green solution, as a result of the compound breaking apart into individual Cu2+ and Cl- ions. When the water was first mixed with the copper chloride, it dissolved the solid pretty slowly, turning into a sort of mush at first. However, eventually, the water dissolved all of the solid copper chloride and the solution was homogenous. Since the compound just changed physical form, from solid to liquid, this change was purely physical. Just as in the first part of the experiment, the chemical character of the compound was not altered, so the compound did not experience a chemical change.

In this reaction NaOH was added to the Cu(NO3)2. The solution developed a precipitate which made the clear solution become cloudy and uniform in color (blue). The physical color change was demonstrated through the formation of the precipitate. The third step was the formation of CuO. In this reaction, the Cu(OH)2 product was heated on a hot plate and stirred continuously until the solution became colorless and a dark precipitate formed.

Abstract In this experiment the separation of a copper (II) chloride and sodium chloride mixiture was attempted. The main aim was to separate the compounds from eachother while receiving as much of the original mass of both substances as possible - in perfect conditions the original mass will be received after seperation. Many techniques were considered but dissolution, filtration and evaporation proved to be easiest and most reliable in a school environment with school equipment. The copper (II) chloride and sodium chloride mixture was dissolved in a methanol solution and filtered out leaving the sodium chloride behind.

Title: THE BALLOON INFLATION REACTION Introduction: Chemistry is one thing that makes us understand and gives us reasons of why certain reactions gives certain results. In this experiment we will be illustrating the reaction between baking powder and vinegar and see what happens to the balloon that is attached to it. Hypothetically the reaction of the vinegar and baking powder will produce carbon dioxide which will inflate the balloon. If the more vinegar may happen that when more vinegar is added to the baking powder it may produce more carbon dioxide thus the balloons diameter increases.

The wax melted first, followed by the salt, and lastly the sugar. The salt not only burned before the sugar, but developed a brown color throughout most of the substance at a faster pace. In the water solubility test, the salt dissolved in the water, as soon as it was properly mixed and the sugar dissolved in the water as well, but was stirred for a longer period of time until it was completely dissolved. The wax did not dissolve in the water, however bits of the substance broke off from the main piece. With this information, the final results included: wax as a nonpolar covalent compound, since the substance melted first and was not soluble in water; salt as a polar covalent compound, since the substance was soluble in water and the second to melt; and sugar as an ionic compound because the substance melted last and was soluble in
