WebWhy H 3 P O 4 is triprotic acid but H 3 P O 3 is diprotic acid? Medium. View solution > The tribasic acid is : Medium. View solution > Phosphoric acid is a triacidic acid. Medium. View solution > WebAn example of a triprotic acid is orthophosphoric acid (H3PO4), usually just called phosphoric acid. Another example of a triprotic acid is citric acid, which can successively lose three protons to finally form the citrate ion. Triprotic acids can make three distinct proton donations, each with a unique Ka. Diprotic and Polyprotic Acids

WebPhosphoric acid: The chemical structure of phosphoric acid indicates it has three acidic protons. Diprotic Acids With a Very Weak Second Dissociation Step When a weak diprotic acid such as carbonic acid, H 2 CO 3, dissociates, most of the protons present come from the first dissociation step: WebSep 13, 2024 · Phosphoric acid (H3PO4) is tribasic, with pKa's of 2.14, 6.86, and 12.4. The pKa value is method to indicate the acid strength. It is the negative log of the acid dissociation constant or Ka value. A lower pKa value indicates a stronger acid. Hence the lower value indicates the acid more fully dissociates in water. braintree road test route
