Solution

Definition of acid:
An acid is a substance in which the only positive ion is hydrogen. It can be replaced by a metal or basic radical.
Acid can be classified as dilute or concentrated depending on the concentration of the hydrogen ions in it.
Dilute acid
A dilute acid is one in which the water's concentration mixed in the acid is greater than the acid's concentration itself.
With the addition of water, a concentrated acid can be diluted. This reaction is exothermic.
