Question

Why does an aqueous solution of an acid conduct electricity?

Answer 1

Because all acid aqueous solutions are conductive, due to the presence of hydrogen ions and acid ions, which can conduct charge exchange between the electrodes and thus conduct electricity. So the acid is also an electrolyte.

Take hydrochloric acid for example:

An acid is essentially an substance, that splits into an proton (H+) and an negative rest an anion (Cl-) in aqueous solutions. The proton takes the role of a “transmitter“ it leads electrons (e-) through the liquid.

Hope this will help you.... ✌

Answer 2

as you know that electricity is flow of charges.
in aqueous solutions of acids ions are formed
i,e H+ . ions are responsible for conduction of electricity in these solutions.
