Anode (Oxidation):

• Na(aq) → Na⁺(aq) + e^-

  This is an oxidation reaction because sodium loses an electron, resulting in an increase in its oxidation state (0 to +1).

Cathode (Reduction):

• 2H₂O(l) + 2e^- → H₂(g) + 2OH^-(aq)

  This is a reduction reaction because hydrogen gains electrons, resulting in a decrease in its oxidation state (0 to -1).
