Question

Sodium chloride conducts electricity in the molten state, while it behaves as an insulator in the solid state.

• A. True
• B. False

Answer 1

The correct option is A True

The Solid state of NaCl does not have free electrons and hence it does not contain electricity. In the molten state, NaCl exits as ions of $Na+$ and $Cl-$. Thus these ions help to conduct electricity. Hence the above statement is true.
