Ionic solids conduct electricity in molten state but not in solid state because

Question

Ionic solids conduct electricity in molten state but not in solid state because (A) in molten state free ions are furnished which are not free to move in solid state (B) in solid state ionic solids are hard, brittle and become soft in molten state (C) all solids conduct electricity in molten state (D) in solid state ions are converted to atoms which are insulators

Tardigrade Admin · Accepted Answer

Ionic solids conduct electricity in molten state since in molten state ionic solids dissociate to give free ions which in solid state are not free to move and are held together by strong electrostatic forces of attraction.

Q. Ionic solids conduct electricity in molten state but not in solid state because

in molten state free ions are furnished which are not free to move in solid state

in solid state ionic solids are hard, brittle and become soft in molten state

all solids conduct electricity in molten state

in solid state ions are converted to atoms which are insulators

Ionic solids conduct electricity in molten state since in molten state ionic solids dissociate to give free ions which in solid state are not free to move and are held together by strong electrostatic forces of attraction.
