why does an aqueous solution of an acid conduct electricity

An aqueous solution of an acid conducts electricity because acids dissociate in water to form ions. These ions are charged particles that can move freely in the solution, allowing it to conduct electric current. For example, hydrochloric acid (HCl) dissociates into hydrogen ions (H+) and chloride ions (Cl-) in water. The hydrogen ions combine with water molecules to form hydronium ions (H3O+), which also carry charge. These free-moving ions are responsible for conducting electricity in the solution. In summary, the ability of an aqueous acid solution to conduct electricity is due to the presence of mobile ions formed by the dissociation of the acid in water.
