Chemical Bonding And Molecular Structure

Question

Wired Faculty App

Can sodium chloride conduct electric current in the solid state?

Solution

No, sodium chloride can not conduct electricity in the solid state. This is because oppositely charged ions (Na⁺ and Cl^– ions) are held together by a strong electrostatic force of attraction. These ions occupy fixed positions in the crystals and do not move when an electric field is applied.
