उत्तर २

Due to charged particles, there is electricity that is conducted in aqueous solutions. The charged particles are called ions and they help conduct electricity.

उत्तर ३

Acids dissociate to release H+ ions and an anion, when dissolved in water. When electric current is passed through an aqueous solution, the ions start moving toward oppositely charged terminals of the battery, henceforth, conducting electricity.
