Question

why does a aqueous solution of acid conduct electricity

Answer 1

Because an aqueous solution of an acid contains free moving ions due to which it conducts electricity.....REMEMBER IT HAS FREE IONS NOT FREE ELECTRONS....

Answer 2

Why does the aqueous solution of acid conduce electricity?

Answer :-

The aqueous solution of an acid contains free ions .That is why it can conduct electricity.

Details :

The acid is a compound which dissociates in aqueous solution to give a large concentration of hydrogen ions.

Thus these hydrogen ions are free ions which can stay in a solution.

Thus  acid can easily conduct electricity because electricity is nothing but the movement of free electrons.
