Solution: Calculate Eocell for the following balanced redox reaction.O2(g) + 2H2O(l) + 4Ag(s) → 4OH−(aq) + 4Ag+(aq)

Solution: Calculate Eocell for the following balanced redox reaction.O2(g) + 2H2O(l) + 4Ag(s) → 4OH−(aq) + 4Ag+(aq)

Problem

Calculate Eocell for the following balanced redox reaction.

O2(g) + 2H2O(l) + 4Ag(s) → 4OH(aq) + 4Ag+(aq)

Solution

First step is to split the overall reaction into half reactions

The half reactions are:
Ag(s) → Ag+(aq) + e- (Anode : oxidation)
