Quizplus · Accepted Answer

Triprotic acids have three dissociable protons. Phosphoric acid is a triprotic acid as it can lose three protons in three stages to form three different conjugate bases: H2PO4-, HPO42-, and PO43-. The other options listed are either monoprotic (such as Benzoic and Formic acid) or diprotic (such as Acetic acid and Nitric acid).
