Question
Define an acid.
✓

Answer

An acid is defined as a compound which when dissolved in water produces hydronium ion $(H_3O^+)$, the only positively charged ion and a negative ion. At first the acid furnishes hydrogen ion $(H^+)$ in aqueous solution but this $H^+$ ion combines with a water molecule to form Hydronium ion.
For example : acetic acid, sulphuric acid, nitric acid.
$CH_3COOH + H_2O → H_3O^+ + CH_3COO^-$​​​​​​​
