Question

Compare the electrolysis of molten potassium chloride and solution of potassium chloride. What are the processes taking place at the cathode and the anode?​

Answer 1

Answer:

when molten kcl

k+ and cl-

At Cathode:-

K+e-=K

At Anode:-

2cl- =2cl+2e-

When solution of Kcl then discharge potential method works

K+ cl- H+ Oh-

At anode:-

2cl- =cl2 +2e-

At cathode:-H20+e- = H2 + Oh-
