Question

Differentiate between electrolytic refining and electrolytic reduction...

Plz answer from any good guide of class 10
The best answer would get brainliest!!!

Answer 1

✷In electrolytic reduction current is passed through the metal oxide to reduce it to pure metal whereas in electrolytic refining the impure metal is converted into pure metal.

Some of the differences are given below:

1) In electrolytic reduction graphite electrodes are used which are of same size,whereas 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.

2) 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.

USE OF ELECTROLYTIC REFINING:

Electrolysis, or electrolytic refining, is a technique used for extraction, as well as purification, of metals obtained by any refining method. 

USE OF ELECTROLYTIC REDUCTION:

Electrolytic reduction is the method of reducing metals with the help of electrolysis .

Answer 2

a. 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. initially the cathode is thick and the anode is very thin. 

b. the electrolyte used in electrolytic refining is the metal sulphate with acid (acid id added to increase the conductivity) which is aqueous in nature. whereas in electrolytic reduction molten chloride form of the solution is used.

Hope this will help you ^_^
