It is a conjugate acid of phosphate [PO 4] 3-and a conjugate base of dihydrogen phosphate [H 2 PO 4] −. It is formed when a pyrophosphate anion [P 2 O 7] 4− reacts with water H 2 O by hydrolysis, which can give hydrogenphosphate: [P 2 O 7] 4− + H 2 O ⇌ 2 [HPO 4] 2−

Dihydrogen phosphate is an inorganic ion with the formula [H 2 PO 4] −.Phosphates occur widely in natural systems. [1]These sodium phosphates are artificially used in food processing and packaging as emulsifying agents, neutralizing agents, surface-activating agents, and leavening agents providing humans with benefits.
The last one is pyrophosphate [P 2 O 7] 4−. The pyrophosphates are mostly water-soluble. Likewise, tripolyphosphoric acid H 5 P 3 O 10 yields at least five anions [H 5−k P 3 O 10] k−, where k ranges from 1 to 5, including tripolyphosphate [P 3 O 10] 5−. Tetrapolyphosphoric acid H 6 P 4 O 13 yields at least six anions, including ...
It is the conjugate base of the hydrogen phosphate ion H(PO 4) 2−, which in turn is the conjugate base of the dihydrogen phosphate ion H 2 (PO 4) −, which in turn is the conjugate base of orthophosphoric acid, H 3 PO 4. Many phosphates are soluble in water at standard temperature and pressure.
A phosphite anion or phosphite in inorganic chemistry usually refers to [HPO 3] 2− but includes [H 2 PO 3] − ([HPO 2 (OH)] −). These anions are the conjugate bases of phosphorous acid (H 3 PO 3). The corresponding salts, e.g. sodium phosphite (Na 2 HPO 3) are reducing in character.

The anhydrous acid can be formed by vacuum dehydration over P 4 O 10 or by the reaction of H 2 S on lead hypophosphate, Pb 2 P 2 O 6. [1] Hypophosphoric acid is tetraprotic with dissociation constants pK a1 = 2.2, pK a2 = 2.8, pK a3 = 7.3 and pK a4 = 10.0. [1] On standing the anhydrous acid undergoes rearrangement and disproportionation to form ...
