Question

Ionic solids conducts electricity in molten state but not in solid state .Why ? Give the reason.

Answer 1

In ionic compounds, electricity is conducted by ions. In solid state, ions are held together by strong electrostatic forces and are not free to move about within the solid. Hence, ionic solids do not conduct electricity in solid state. However, in molten state or in solution form, the ions are free to move and can conduct electricity.

Answer 2

Ionic solids conduct electricity in molten state not in solid state because only in molten state they are able to lose or gain electrons or to converts into ions so for their ionisation their molten state is necessary
