In electrolytic refining of copper, the electrolyte is a solution of

Options

  1. Aacidified copper chloride.
  2. Bacidified copper sulphate.
  3. Cpotassium chloride.
  4. Dsodium sulphate.

Correct answer

B. acidified copper sulphate.

Step-by-step solution

- Electrolytic refining is the process of refining impure metals by using electricity. In this process impure metal is made as 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. - In electrolytic refining of copper, the electrolyte is a solution of acidified copper sulphate. The anode is impure copper, whereas the cathode is a strip of pure copper on passing electric current, pure copper is deposited on the cathode.
