Answer:
It means the charge is taken away from the potassium and chloride ions at the electrodes.
Explanation:
The solution may be represented by K+(aq)andCl−(aq)
At the positive electrode (anode) the following happens:
Cl−→Cl+e−
2Cl→Cl2(g)
At the other side (cathode):
K++e−→K
K+H2O→K++OH−+H
2H→H2(g)
So the net result is that at the anode chlorine gas is released, at the cathode hydrogen gas is released, and a strong solution of potassium hydroxide is left in the container:
