$H_2, O_2$

Vedclass · Answer

(C) solution of sodium sulphate in water is electrolysed using inert electrodes. The products at the cathode and anode are $H_2$ and $O_2$ respectively.At the cathode,hydrogen ions $(H^+)$ have a higher reduction potential than sodium ions $(Na^+)$,so they are reduced to hydrogen gas:$2H^+ + 2e^- \rightarrow H_2 \uparrow$At the anode,hydroxide ions $(OH^-)$ have a lower discharge potential than sulphate ions $(SO_4^{2-})$,so they are oxidized to oxygen gas:$4OH^- \rightarrow 2H_2O + O_2 + 4e^-$
