Ionic Theory
In solutions, electrolytes are present in the form of ions and permits the flow of current through them.
Movement of ions is responsible for the flow of current.
Sodium chloride is an electrolyte that will conduct electricity either in aqueous solutions or in molten state.
Molten and solid form of Sodium chloride
Sodium chloride is an ionic compound that involves the presence of sodium and chloride ions.
In molten form, these ions are free to move. Therefore, molten sodium chloride is decomposed by electric current.
In solid-state, these ions are not allowed to move freely, and due to this, solid sodium chloride is a poor conductor of electricity in the solid state.
Strong electrostatic attractions hold the constituent ions tightly and makes them unable to move in solid state.
Hence, is a poor conductor of electricity in the solidstate.
