Which one of the following condition will increase the voltage of the cell represented by the equation : `Cu_((s))+2Ag_((aq))^(+)hArr Cu_((aq))^(+)+2Ag_((s))`

Options

A. increase in the dimension of Cu electrode
B. increase in the dimension of Ag electrode
C. increase in the dimension of `Cu^(2+)` ions
D. increase in the dimension of `Ag^(+)` ions

Answer

D

Explanation

Since reduction occurs at Ag electrode, hence increase in the concentration of `Ag^(+)` or decrease in concentration of `Cu^(2+)` will increases the voltage.
