Can sodium chloride conduct eletricity in the solid state ?

A

Solids do not conduct electricity.

B

The ions of NaCl become mobile only in molten state and are not free to move in solid state.

C

The crystalline structure does not have ions.

D

When a bond is formed between ions they lose their charges.

Text Solution

Verified by Experts

The correct Answer is:
B
Due to electrostatic force of attraction, the ions do not move when electric current is applied in solid state. The ions become mobile when melted or dissolved in a polar solvent and conduct electricity.
