Question

Which of the following sentences about conduction is/are true?

• A. Electrolytic conduction involves transfer of matter
• B. Metallic conduction does not involve transfer of matter
• C. Both of the above
• D. None of the above

Answer 1

The correct option is C Both of the above

In electrolytic conduction, a voltage is applied across the electrodes dipped into the electrolytic solution. There are ions present in electrolytic solution. Because of the voltage applied, electric current will flow in the solution. The ions will move in the solution. The cations will move towards the cathode, whereas the anions will move towards the anode.
Thus in electrolytic conduction mass is transferred in the form of ions.
Whereas, no such transfer of mass occur in metallic conduction. It is just the flow of electrons.
