dilute aqueous solution of $NaCl$

Vedclass · Answer

(C) In the electrolysis of a dilute aqueous solution of $NaCl$,water undergoes oxidation and reduction at the electrodes.At the cathode,the reduction of water occurs: $2H_2O(l) + 2e^- \rightarrow H_{2(g)} + 2OH^-(aq)$.At the anode,the oxidation of water occurs: $2H_2O(l) \rightarrow O_{2(g)} + 4H^+(aq) + 4e^-$.Thus,$H_{2(g)}$ is produced at the cathode and $O_{2(g)}$ is produced at the anode.

Which of the following will give $H_{2(g)}$ at cathode and $O_{2(g)}$ at anode on electrolysis using platinum electrodes?
