Q39 / 180 · KCET 2018 · Chemistry

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

  • Correct answer
    A
    \( \mathrm{Cu} \) and \( \mathrm{Zn} \)
  • B
    Ge and Si
  • C
    \( \mathrm{Zr} \) and \( \mathrm{Ti} \)
  • D
    \( \mathrm{Zn} \) and \( \mathrm{Hg} \)

Solution

Electrolytic Refining is used to purify Cu and \( \mathrm{Zn} \). 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.

Hence, the correct answer is option: 'A'.
