Why does an aqueous solution of acid conduct electricity?
Electricity is the movement of charge from one place to another place. It needs a medium which allows movement of charges. Acids in aqueous solution mean acid in water aka diluted acids. Polar nature of water splits the acid molecules into its cations and anions. Cations and anions are charged particle and are free to move inside the aqueous medium. As a result when a potential difference has applied the solution to conduct electricity.
HA + H2O —> H3O+ + A–
Distilled water ( water without minerals, ions etc ) do not conduct electricity.
Not only acids, but all salts and bases also make the aqueous medium more conductive.
