iii. Write the electrode reactions during electrolysis of molten KCl.


Electrode reactions during the electrolysis of molten KCl are as follows:

Oxidation half-reaction at anode:

\[2\ce{Cl^-_{(l)}} \rightarrow \ce{Cl2_{(g)}} + 2e^-\]

Reduction half-reaction at cathode:

\[2\ce{K^+_{(l)}} + 2e^- \rightarrow 2\ce{K_{(l)}}\]
