The standard potential of the galvanic cell, Sn(s) | Sn2+(aq) || Cu2+(aq) | Cu(s) is 0.48 V. Starting with standard concentrations, what are the concentrations of Sn2+(aq)and Cu2+(aq) when the cell has discharged so that the potential is 0.45 V?

Answers:

a. [Sn2+(aq)] = [Cu2+(aq)] = 1.0 M

b. [Cu2+(aq)] = 0.47 M, [Sn2+(aq)] = 1.53 M

c. [Sn2+(aq)] = 0.47 M, [Cu2+(aq)] = 1.53 M

d. [Cu2+(aq)] = 1.82 M, [Sn2+(aq)] = 0.18 M

Correcte. [Sn2+(aq)] = 1.82 M, [Cu2+(aq)] = 0.18 M
