Question

Shown below is an clcctrolytic cell. Both the anode and the cathode arc inert clectrodes. The liquid shown in compartment b of the cell is molten potassium chloride, KCI(I). What arc the reactions occurring at the anode and cathode, respectively? Anode reaction: 2 Cl-(l) rightarrow Cl2(g) + 2e-; Cathode reaction: K+(l) + e- rightarrow K(s) Anode reaction: Cl2(g) + 2e- rightarrow 2 Cl-(l); Cathode reaction: K(s) rightarrow K+(l) + e- Anode reaction: K(s) rightarrow K+(l) + e-; Cathode reaction: Cl2(g) + 2e- rightarrow 2 Cl-(l) Anode reaction: K+(l) + e- rightarrow K(s); Cathode reaction: 2 Cl-(l) rightarrow Cl2(g) + 2e- None of the above; it is not possible to clcctrolyzc a molten salt.

Explanation / Answer

Option (a) is correct.

KCL has K+ and Cl- ions.

So, those are the reactions that take place at the respective electrodes.
