Q. When $CuSO_4 $ is electrolysed using platinum electrodes?

AIPMTAIPMT 1993The d-and f-Block Elements

Solution:

During electrolysis, copper is deposited at the cathode while oxygen is liberated at anode. The following reactions occur at the electrodes
At anode $ 2 H _{2} O \longrightarrow 4 H ^{+}+ O _{2}+4 e^{-}$(Oxidation)
At cathode $Cu ^{2+}+2 e^{-} \longrightarrow Cu (s)$ (Reduction)
