Question

Mark the correct option:
a) Pure metal from the electrolyte is deposited at the anode.
b) The soluble impurities go into the solution.
c) Insoluble impurities known as anode mud.

• A. a, b
• B. b, c
• C. a, c
• D. All statements are correct

Answer 1

The correct option is B b, c

On passing the current through the electrolyte, pure metal from the anode dissolves into the electrolyte. An equivalent amount of pure metal from the electrolyte is deposited on the cathode.
The soluble impurities get dissolved in the electrolytic solution and the insoluble impurities settle down below the anode and are known as Anode mud.
Thus, Option $B$ is correct
