Question

Answer the following in one or two sentences.

Write the electrode reactions during electrolysis of molten KCl.

Answer 1

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

\[\ce{2Cl^{-}_{ (l)}  -> Cl2_{(g)} + 2e^{-}}\] (Oxidation half-reaction at anode)

\[\ce{2K^{+}_{ (l)} + 2e^{-} -> 2K_{(l)}}\] (Reduction half-reaction at cathode)
                                                                                                                  
\[\ce{2K^{+}_{ (l)} + 2Cl^{-}_{ (g)}  -> 2K_{(l)} + Cl2_{(g)}}\] (Overall cell reaction)
