Question

Brine is electrolysed by using inert electrodes. The reaction at anode is .................
(a) $Cl^- (aq) \longrightarrow \frac{1}{2} Cl_2 (g) + e^-$; $E^{\ominus}_{cell}$ = 1.36 V
(b) $2H_2O(l) \longrightarrow O_2(g) + 4H^+ + 4e^-$; $E^{\ominus}_{cell}$ = 1.23 V
(c) $Na^+ (aq) + e^- \longrightarrow Na(s)$; $E^{\ominus}_{cell}$ = 2.71 V
(d) $H^+ (aq) + e^- \longrightarrow \frac{1}{2} H_2 (g)$; $E^{\ominus}_{cell}$ = 0.00 V
