Question

Solid $NaCl$ is a bad conductor of electricity because :

• A. Solid $NaCl$ is covalent
• B. In solid state there are no ions
• C. In solid $NaCl$, there is no migration of ions
• D. In solid $NaCl$ , there are no electrons.

Answer 1

The correct option is C In solid $NaCl$, there is no migration of ions

In solid $NaCl$, there is a strong force of attraction and ions cannot move from one place to another i.e. ions cannot migrate. Hence it does not conduct electricity.
