At the molten state or in solution, the ions are free.

Explanation:

Salts do not conduct electricity at the solid state since the ions are in a fixed position in the lattice.

However, at the molten state or in solution, the ions are free and they can move within the liquid phase to serve as electrons shuttles and therefore, they become conductive.
