Ionic compounds in the solid state do no...

Ionic compounds in the solid state do not conduct electricity but conduct electricity in the molten state. Justify the statement.

Text Solution

Verified by Experts

1. The ionic compounds cannot conduct electricity when in solid state, because in solid state the ions cannot leave their places.
2.However, in the molten state they can conduct electricity, as in this contain the dissociated ions.
4. On passing current through the solution the ions move to the oppositely charged electrodes.
