Electrolytic Conduction Worksheet

Those conduction which involve the movement of ions is called electrolytic conduction. Example of electrolytic conduction is solution of Nacl and water. It can also be said as, “the condition in which the electrical current flows through the ions on a solution or pure liquid.”
