Question

explain why aqueous solution of an acid conduct electricity but gaseous form do not ​

Answer 1

Electric current flows through the solution by ions. Since dry hydrochloric acid does not give any ions, it does not conduct current. Whereas in the presence of water, H+ ions and CI– ions are produced which are responsible for flow of current.

Answer 2

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.
