Answer to Question #56944 in General Chemistry for julie g

Question

A battery is constructed at 25ºC using the voltaic cell with initial concentrations

Zn│Zn2+ (0.100 M) ││Ag+ (1.500 M) │Ag

How much does the cell voltage drop when 95% of the capacity (i.e., the concentration of Ag drops to 5% of its starting value) is consumed?

The standard reduction potentials for the two half-cells are
+
Zn2+ + 2e- → Zn Eº = − 0.76 V
Ag+ + e- → Ag Eº = 0.80 V
