2.1 Difference between metallic conduction and electrolytic conduction

Metallic Conduction	Electrolytic Conduction
$(i)$ Current flows by the movement of electrons	$(i)$ Current flows by the movement of ions

$(iii)$ Ohm law is applicable	$(iii)$ Ohm's law is applicable
$(iv)$ No chemical changes occur	$(iv)$ Chemical changes occur as ions are either reduced or oxidized at the electrodes.
$(v)$ Resistance increases with the increase in temperature	$(v)$ Resistance decreases with the increase in temperature
$(vi)$ Faraday's law is not valid	$(vi)$ Faraday's law is valid
