Ionic solids do not conduct electricity but will when the temperature is raised above the melting point.
Which of the following explains why this is possible?
The ionic solid dissociates, and the resultant solution allows for conduction based on the solute-solvent interaction.
The energy added to the system causes a breakdown in the crystalline structure, which allows for free movement of the ions.
The energy added to the system is actually absorbed in the form of an electrical charge, allowing the ionic compound to then conduct that charge.
Ionic compounds can only conduct electricity when dissolved in water.
