Potassium Chloride conducts electricity in a molten state. The movement of ions takes place only in a molten state
Why potassium chloride conducts in a molten state?
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 o does not conduct electricity because the ions are held firmly in place. The ions cannot move to conduct the electric current. K+ and Cl– ions become fully dissociated in the water, where the mobile ions can freely drift under an electrical field’s influence.
