Answer 1

Answer:

Hey mate here's your answer...

Explanation:

(a) Electrolytic refining

(b) It is a process of refining a metal by the process of electrolysis . In the electrolysis refining of copper , the electrolyte used is acidified copper sulphate .

Impure metal - anode  

pure metal - cathode

[in simple language pure metal cathode side aa jayega or it will deposit on cathode and impure one will deposit on anode]

At cathode :- Cu  ⇒  $Cu^{2+}$  + $2e^{-}$

At anode :-  $Cu^{2+}$  + $2e^{-}$  ⇒ Cu

The soluble impurities go into the solution and insoluble settle down at the bottom of anode and are known as anode mud .

(c)   Uses

Many metals, such as copper, zinc,  tin, nickel, silver, gold, etc., are refined electrolytically.
