Homework Help: Standard Reduction Potentials of 1/2 Cells

  1. Mar 31, 2007 #1
    1. The problem statement, all variables and given/known data
    Use half-reactions and E's to determine the result of storing a solution of CuSO4 in a tin container.

    2. Relevant equations
    [Table of Standard Reduction Potentials of Half-Cells]

    3. 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+ ?

    Which has the greater standard reduction potential? The one for cuprous ion or the one for the tin ion? Check in you table of standard reduction potentials.

    well then how do u know Cu2+ will ever react to form Cu+? Because the reaction that yields Cu(s) always has a high reduction potential.
