Conceptual: Consider a Sn(s)|Sn2+(aq) || Cu2+(aq)|Cu(s) cell. If the Sn2+ concentration is increased, what will happen to the measured Ecell value?

• Calculation, full-reaction Nernst equation: Use the full Nernst equation to calculate Ecell for the conditions described…

• Easier: Ni | Ni2+(0.300 M) || Cu2+(0.002 M) | Cu

• Harder: Al | Al3+(0.002 M) || Cu2+(4.00 M) | Cu

• Calculation, half-reaction Nernst equation: Use the Nernst equation to calculate E at pH 3.00 and [Cl- ] = 0.0035 M for this reduction half-reaction.

BiOCl(s) + 2H+ (aq) + 3e- ⇌ Bi(s) + H2O(l) + Cl- (aq) E=0.160
