Materials- Copper (II) chloride, aluminum foil, beaker, water, scale, and test tube.
Procedure- In this lab, it is all about measurement, and figuring out which ratio is correct. The first thing we did was what any good chemistry student would do. We went with trial and error. Any amount that looked good to us we went with and figured even if it wasn't right we would still get to see a reaction. After several attempts I decided that it was time to get a better calculation to start getting the max reaction. So I went to the periodic table, and added the mass off Cu, Cl, and Al. After I had the total (125.981) I divided Al by the total. This shows that just over 20 percent of the mass is Aluminum. So now we had some kind of measurement to go off of. With a 4 CuCl to 1 Al ratio we went to work. First you have to weigh each substance and get 4 grams and 1 gram. Then you put the CuCL in the test tube and mix it with water. When it looks as if all of it has dissolved into the water you throw in the Aluminum. The aluminum then reacts to the mixture, and starts fizzing and bubbling. The reaction was much greater this time, after we had the weights to go off of. The substance was poring out of the test tube, and we almost got the Aluminum to come out of the test tube.
Conclusion- In conclusion this was a very fun and exiting lab. I learned a lot from this lab, like how to save your substances from just being pored to find the right amount. It always saves time and chemicals to find out how much of each to use. Not to mention that it also causes a much bigger reaction. So all in all this was a great lab, I learned a lot and we got to cause major reactions.
