When an aqueous solution of sodium sulfate, Na2SO4\text{Na}_2\text{SO}_4Na2SO4, is electrolysed using inert platinum electrodes, gaseous products are liberated at both the cathode and the anode.
Explain, with reference to the ions present and their relative reactivity or ease of discharge, the formation of the products at each electrode.
