The aqueous solution of an acid conducts electricity due to the presence of charged particles called ions in it. for example, when hydrochloric acid ` (HCl)` is dissolved in water, then its aqueousl solution contains hydrogen ions ` [H^ (+) (aq)]` and chloride ions [`Cl^ (-)` (aq)]. These ions carry electric current. Conclusion: Therefore, the ability of an aqueous solution of an acid to conduct electricity is primarily due to the presence of free-moving H⁺ ions and other ions that result from the dissociation of the acid in water. --- The presence of hydrogen (H +) or hydronium (H 3 O +) ions in the aqueous solution of an acid are responsible for conducting electricity. Due to charged particles, there is electricity that is conducted in aqueous solutions. The charged particles are called ions and they help conduct electricity. The presence of hydrogen (H +) or hydronium (H 3 O +) ions in the aqueous solution of an acid are responsible for conducting electricity.
