Question

The reactions taking place at anode and cathode of a cell respectively are :

• A. reduction, oxidation
• B. oxidation, reduction
• C. hydrolysis, oxidation
• D. reduction, hydrolysis

Answer 1

The correct option is B oxidation, reduction

At anode oxidation takes place as shown below:
$M\to M^{+}+e^{-}$
or $M^{-}\to M+e^{-}$
and at cathode reduction takes place as shown below:
$e^{-}+M\to M^{-}$
or $M^{+}+e^{-}\to M$
