Vedclass · Accepted Answer

Pure ionic solids are good conductors of electricity in the solid state.

Vedclass · Answer

(D) Ionic solids consist of ions held together by strong electrostatic forces of attraction,making them hard and brittle. However,in the solid state,the ions are fixed in their lattice positions and are not free to move. Therefore,they are poor conductors of electricity in the solid state. They only conduct electricity when molten or dissolved in water,as the ions become free to move. Thus,statement $D$ is incorrect.
