Question

# Potassium chloride conducts electricity in _______ state.

Open in App
Solution

## Molten state of potassium chloride:The melting process frees the ions in potassium chloride from their fixed positions in the crystal lattice. Since these ions can move freely under the influence of an electric field, they can conduct electricity. Solid ionic compounds do not conduct electricity because the ions are held firmly in place. The ions cannot move to conduct the electric current.${\mathrm{K}}^{+}$ and ${\mathrm{Cl}}^{–}$ ions become fully dissociated in the water, where the mobile ions can freely drift under an electrical field’s influence.Hence, the movement of ions takes place only in the molten state.Therefore, potassium chloride conducts electricity in a molten state.
