Phosphoric acid - Wikipedia

Phosphoric acid (also known as orthophosphoric acid or phosphoric(V) acid) is a weak acid with the chemical formula H 3 P O 4. Orthophosphoric acid refers to phosphoric acid, which is the IUPAC name for this compound. The prefix ortho-is used to distinguish the acid from related phosphoric acids, called polyphosphoric acids.

Lecture 16: Polyprotic Acids - University of Texas at Austin

polyprotic acids. This is one of the reasons we choose to look at carbonic acid and phosphoric acid—aside from being incredibly important in our daily lives, they also permit all the approximations we have learned and allow us to pretend to be doing polyprotic acid calculations when we are actually performing monoprotic acid calculations.

Determination of phosphoric acid concentration by alkalimetric titration. general remarks. Titration of the phosphoric acid H 3 PO 4 is an interesting case. Although often listed together with strong mineral acids (hydrochloric, nitric and sulfuric) phosphoric acid is relatively weak, with pK a1 =2.15, pK a2 =7.20 and pK a3 =12.35. That means titration curve contains only two inflection points ...

Diprotic and Triprotic Acids and Bases - Purdue University

Diprotic Acids. The acid equilibrium problems discussed so far have focused on a family of compounds known as monoprotic acids.Each of these acids has a single H + ion, or proton, it can donate when it acts as a Brnsted acid. Hydrochloric acid (HCl), acetic acid (CH 3 CO 2 H or HOAc), nitric acid (HNO 3), and benzoic acid (C 6 H 5 CO 2 H) are all monoprotic acids.
