MCQ
Identify the false statement among the following:
  • A
    Oxidation takes place at positive electrode in electrolytic cell whereas at negative electrode in voltaic cell.
  • ✓
    Deposition of metals takes place in both electrolytic cell and galvanic cell.
  • C
    Direction of flow of current is from cathode to anode in electrolytic cell.
  • D
    Both $A$ and $B.$
✓

Answer

Correct option: B.
Deposition of metals takes place in both electrolytic cell and galvanic cell.
Oxidation takes place at anode and reduction at cathode. In electrolytic cell anode is positive and anode positive. In voltaic cell, anode is negative.
Metal deposition takes place in electrolytic cell only.
Direction of current is always cathode to anode in electrolytic cell.
