Why does an aqueous solution of an acid conduct electricity?

Charged particles are responsible for the conductance of electricity in an acid. Aqueous solutions of acids conduct electricity signifies the existence of ions in these solutions.
Acids dissociate 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 \( H_2 \) gas. Because of this reaction, an aqueous solution of acid conducts electricity.
