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.
This bonding mode is illustrated by [Mo 2 (HPO 4) 4] 4−, which features a Mo-Mo triple bond. [3] Related [Pt(III)] 2 complexes have been reported. [4] Tridentate, bridging. Several triangulo clusters feature a capping phosphate ligand, e.g. [Re 3 Cl 9 (PO 4)] 3−. [5] Encapsulated: In phosphotungstic acid, all four oxygen atoms of phosphate ...
Their salts are used in fertilizers and in cooking. [1] Most hydrogenphosphate salts are colorless, water soluble, and nontoxic. 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 ...
At pH 1 or lower, the phosphoric acid is practically undissociated. Around pH 4.7 (mid-way between the first two pK a values) the dihydrogen phosphate ion, [H 2 PO 4] −, is practically the only species present. Around pH 9.8 (mid-way between the second and third pK a values) the monohydrogen phosphate ion, [HPO 4] 2−, is the only species ...
Cycloalkanes and aromatic compounds can be treated as the main parent chain of the compound, in which case the positions of substituents are numbered around the ring structure. For example, the three isomers of xylene CH 3 C 6 H 4 CH 3 , commonly the ortho- , meta- , and para- forms, are 1,2-dimethylbenzene, 1,3-dimethylbenzene, and 1,4 ...
The disodium salt can be passed through an ion exchange column to form the acid dihydrate, H 4 P 2 O 6 ·2H 2 O. [2] 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 ...
A typical derivative is the salt [NH 4][HP(O) 2 OH]. [7] [6] Many related salts are known, e.g., RbHPHO 3, CsHPHO 3, TlHPHO 3. These salts are prepared by treating phosphorous acid with the metal carbonate. These compounds contain a layer polymeric anion consisting of HPO 3 tetrahedra linked by hydrogen bonds. These layers are interleaved by ...
Ammonium dihydrogen phosphate (ADP), also known as monoammonium phosphate (MAP) [5] is a chemical compound with the chemical formula (NH 4)(H 2 PO 4). ADP is a major ingredient of agricultural fertilizers [6] and dry chemical fire extinguishers. It also has significant uses in optics [7] and electronics. [8]
