Electrolytic refining is used to purify which of the following metals?

Options

  1. A( Cu ) and ( Zn )
  2. BGe and Si
  3. C( Zr ) and ( Ti )
  4. D( Zn ) and ( Hg )

Correct answer

A. ( Cu ) and ( Zn )

Step-by-step solution

Electrolytic Refining is used to purify Cu and ( Zn ). In this method, impure metal is made anode and a strip of pure metal is made cathode. They are put in a suitable electrolytic solution containing soluble salt of the same metal.
