1)      The water turned blue because we stirred vigorously after about five minutes after putting the copper chloride in the water.

2)      When solutions are made, different results could come out.  A solution is whenever you dissolve something into a liquid, in this case, the water and the copper chloride.

3)      I think what happened is that when the aluminum reacted with the copper chloride, the copper chloride was eating away at the aluminum, forcing it to change into a copper form.

4)      When the nitric acid reacted with the precipitate, I think what happened is that the nitric acid made the copper turn into a liquid, forcing it to bubble and become clear, like the nitric acid was cleaning or filtering the copper precipitate.

5)      The solution turned blue at the end of the experiment because it was bubbling into the blue after we put in the nitric acid.
