Acid and bases conduct electricity
Acids and Bases exhibit their conducting property only if they are in aqueous solution in which they could completely ionize in water. An acid in water solution dissociates H+ ions. Let us consider the reaction between water and hydrochloric acid (HCl). HCl in presence of water produces H+ ion. This ion cannot exist alone and hence combines with water molecules and forms H3O+. The reaction is as follows:
Base when dissolved in water produces OH- ion. Let us consider the reaction between water and sodium hydroxide NaOH. NaOH in presence of water produces OH- ion.
The H+ and OH- ions contain a free electron that carries the electric charge and thereby conducts electricity.
