What is Monoprotic Acid?

A monoprotic acid (monobasic acid) is an acid that can donate only one proton (H⁺) per molecule in an acid–base reaction. Examples include hydrochloric acid (HCl), nitric acid (HNO₃), and acetic acid (CH₃COOH). Monoprotic acids have a single acid dissociation constant (Ka). They are contrasted with diprotic acids (H₂SO₄, H₂CO₃) and triprotic acids (H₃PO₄).
