This week we did a science lab which involved chemicals and such. First we had to fill a beaker with 150mg of water. We then took the temp of the water. It was 20. We then put some copper chloride in the water. The chloride is a green crystal like dust. It turned blue when we stirred it in the water. As we stirred the water it would dissolve. We took the temp and it went to 18 1/2 degrees. So it went down 1 /12 degrees. At this point the blue liquid is all dissolved and blurry. We then put a small strip of tin foil in the liquid. The foil started to decompose and turn a rust color. We started to stir the tin vigorously and it then was completely decomposed. The water was then a reddish gray. We then filtered the water into a flash and only the water went into the flash. When it was done filtering I took the leftover residue from the from the foil and put it in a test tube. We then put
acid in the test tube with the residue. As we examine, it turns a light blue again and starts bubbling. The test tube was also warm. I thought this was a fun experiment
