Answer:
Anode: Zn + Zn2+ → 2e
Cathode: MnO2(s) + NH4+ + e– →MnO(OH) (s) + NH3 (aq)
Answer:
The electrolysis of an aqueous solution of sodium sulphate using inert electrodes produces hydrogen at the cathode and oxygen at the anode and a neutral solution of sodium sulphate remains unaltered by the electrolysis.
At the cathode:
2H+ + 2e– → H2
At the anode:
2H2O → O2 + 4H+ + 4e–
