The pKa values of phosphoric acid are 2.15, 7.20, and 12.35. These values correspond to the three dissociation steps of phosphoric acid, where each hydrogen ion is progressively released to form H2PO4-, HPO4^2-, and PO4^3- ions.

Why is phosphoric acid called a triprotic acid?

Phosphoric acid is called a triprotic acid because it can donate three protons (H⁺ ions) when it is dissolved in water, leading to three dissociation steps and three corresponding Ka values.


What is the difference between ortho-phosphoric acid and phosphoric acid?

Ortho-phosphoric acid is a specific form of phosphoric acid, where the phosphorus atom is bonded to three hydroxyl groups. Phosphoric acid, on the other hand, is a more general term that can refer to any acid containing phosphorus, including ortho-phosphoric acid, as well as pyrophosphoric acid and metaphosphoric acid.
