Question

short note on electrolytic refining ​

Answer 1

$\huge\red{\boxed{\bold{Answer}}}$

$\huge\underline\mathfrak\green{Electrolytic\:refining }:$

• The impure metal is made the anode, and a strip of pure metal is made the cathode.

• A solution of a soluble salt of the same metal is taken as the electrolyte.

• Impurities get collected below the anode and are known as anode mud.

Answer 2

Answer:

Electrolytic refining:- Many metals, such as copper, zinc, tin, nickel, silver, gold etc. are refined by electrolysis. In this process, the impure metal is made the anode and a thin strip of pure metal is made the cathode. The solution of the metal salt is used as an electrolyte.
