In the electrolytic cell, flow of electrons is from

Options

  1. Acathode to anode in solution
  2. Bcathode to anode through external supply
  3. Ccathode to anode through internal supply
  4. Danode to cathode through internal supply.

Correct answer

B. cathode to anode through external supply

Step-by-step solution

In an electrolytic cell, electrons do not flow themselves. It is the migration of ions towards oppositely charged electrodes that indirectly constitutes the flow of electrons from cathode to anode through external supply.
