Copper sulphate solution is electrolysed using copper electrodes.

(i) Which electrode to your left or right is known as the oxidizing electrode and why?

Open in App

Solution

The right electrode is the anode and on anode oxidation takes place due to that, it is known as oxidising electrode.
$C u \to C u^{2 +} + 2 e^{-}$ Here the copper electrode loses two electrons.
