Observations: 1.We measured out one teaspoon of copper chloride dihydrate. 2.The copper appeared to be crystalike and an aqua color. 3.We measured out one fourth a cup of water into a glass. 4.the water was clear/translucent. 5.When the copper cholride dihydrate was added the water turned green and the copper began to dissenegrate. 6.When the mixture was stirred the copper completely dissolved and the water turned more blue. 7.The temperature in the water at this point was 26 degrees celcius. 8.We crumpled up a piece of tinfoil which was around two inches by two inches and was shiny and reflective. 9.We added the tinfoil to the copper and water mixture and it began to react. 10.After a few seconds the foil started ti steam and change colors, from silver to black to a pale pink. 11.The temperature at this point had risen to 58 degrees celcius. 12.In a minute or so the temperature started to decrease abd the foil stopped reacting.

Hypthesis: From this experiment I conclude that the more copper chloride dihydrate you add to a specific amount of water the greater effect it will take on the tin foil. I believe this because the amount of copper and water made the foil dissenegrate faster or slower depending on the amounts.

Test: This could be tested by filling three cups all with the same amount of water and adding different amounts of copper chloride dihydrate and seeing which one dissolves the foil quickest.
