WebSep 1, 2024 · A strong acid is one which completely dissociates in its solvent. Under most definitions, the acid dissociates into a positively-charged hydrogen ion (proton) and a negatively-charged anion. The seven most common strong acids are hydrochloric acid, nitric acid, sulfuric acid, hydrobromic acid, hydroiodic acid, perchloric acid, and chloric acid. WebPhosphoric acid is not a particularly strong acid as indicated by its first dissociation constant. It is a stronger acid than acetic acid, but weaker than sulfuric acid and hydrochloric acid. Each successive dissociation step occurs with decreasing ease. Thus, the ion H. 2. PO. 4 ‾ is a very weak acid, and HPO. 4 2 ‾ is an extremely weak acid.

WebPhosphoric acid is tribasic, each of the hydrogens will dissociate although the final one is very weak indeed. The 3 pKa values are 2.1, 7.2 and 12.7. Although it's not considered a ‘strong' acid, i.e. it is not totally dissociated in water, a 0.1 M solution has a pH of about 1.5, not far off a 0.1 M solution of hydrochloric acid.
