Question

Difference between electrolytic refining and electrolytic reduction in points

Answer 1

<In electrolytic reduction graphite electrodes are used which are of same size.
<In electrolytic reduction no anode mud is formed and in electrolytic refining anode mud is formed from the impurities oh the impure metal
>In electrolytic refining the anode is made of the impure metal which is to be purified
> The electrolyte used in electrolytic refining is the metal sulphate with acid which is aqueous in nature. whereas in electrolytic reduction molten chloride form of the solution is used.

Answer 2

1) In electrolytic reduction graphite electrodes are used which are of same size. in electrolytic refining the anode is made of the impure metal which is to be purified and the cathode is made from that pure metal. ... whereas in electrolytic reduction molten chloride form of the solution is used.
