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.
Concentrated acid:
Concentrated acids are acids that have a high percentage or amount of acid in their aqueous solution.
The percentage of acid dissolved in water determines the concentration of the acid.
Sulfuric acid $(H_{2} {SO}_{4})$ (approximately $98 %$ by weight) used in chemical laboratories is a concentrated acid.
