The standard electrode potential a `Ag^(+)//Ag` is +0.80 V and of `Cu^(2+)//Cu` is +0.34 V. These electrodes are connected through a salt bridge and if :

Options

A. Ag can oxidise Zn and Cu.
B. Ag can reduce `Zn^(2+)` and `Cu^(2+)`
C. Zn can reduce `Ag^(+)` and `Cu^(2+)`
D. Cu can reduce `Zn^(2+)` and `Ag^(+)`.

Answer

C

Explanation

Zinc can reduce `Ag^(+)` and `Cu^(2+)` due to lowest reduction potential.
