The reduction potentials of

Expert Answer:

Oxidation is taking place at Cu electrode and reduction is at Ag.
Hence,
Cu|Cu2+||Ag+|Ag
Cu + 2Ag+......>Cu2+ + 2Ag
 
here, n=2
 
and, Eo=.80-.34=.46V
 
and by using the formula:
 
cell = Eo - (.0592/2) log10 (Cu2+/(Ag+)2 )
 
0=.46V-.0592/2 log(.1/(Ag+)2)
 
Ag+=5*10-9 M
