prove acid solutions conducts electricity by step by step process
Answers
Answer:
Acids undergo dissociation in aqueous solution to form H+ ions. When electricity is passed through an aqueous solution of an acid, the H+ ions reach the cathode and each H+ ion picks up one electron from the cathode to form H2 gas. Because of this reaction, an aqueous solution of acid conducts electricity.
Explanation:
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.
