The electricity is conducted by the solution through the movement of charged particles. A solution of an ionic compound in water contains ions, which move to the opposite electrodes when electricity is passed through the solution. These ions act as carrier of electric current. Ionic compounds conduct electricity in molten state and do not conduct electricity in the solid state. In solid state movement of ions is not possible due to the rigid structure of ionic compounds but in molten state, the electrostatic forces of attraction are overcome by heat and ions move freely and conduct electricity.

Sodium chloride solution contains sodium and chloride ions. The positive sodium ions move towards negative electrode and negative chloride ion move towards positive electrode and thus conduct electricity. Sodium chloride in molten state conducts electricity due to the  presence of freely moving ions and do not conduct electricity in solid state due to its rigid structure and strong electrovalent bonding.
