Use half-reactions and E's to determine the result of storing a solution of CuSO4 in a tin container.

The Attempt at a Solution
My question isn't exactly how to do this question. I was just wondering, how can you tell whether the Cu2+ ion will react in this way: Cu2+ + 2e- ---> Cu(s) or whether it will react like this: Cu2+ + e- ---> Cu+ ?
