Ionic Solid Conduction

APCHEM-KDHEGF

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?

A

The ionic solid dissociates, and the resultant solution allows for conduction based on the solute-solvent interaction.

B

The energy added to the system causes a breakdown in the crystalline structure, which allows for free movement of the ions.

C

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.

D

Ionic compounds can only conduct electricity when dissolved in water.
