Phosphoric acid (orthophosphoric acid, monophosphoric acid or phosphoric (V) acid) is a colorless, odorless phosphorus -containing solid, and inorganic compound with the chemical formula H 3 P O 4. It is commonly encountered as an 85% aqueous solution, which is a colourless, odourless, and non- volatile syrupy liquid.
Phosphoric acids and phosphates. Appearance. Pyrophosphoric acid. In chemistry, a phosphoric acid, in the general sense, is a phosphorus oxoacid in which each phosphorus (P) atom is in the oxidation state +5, and is bonded to four oxygen (O) atoms, one of them through a double bond, arranged as the corners of a tetrahedron.
In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid, a.k.a. phosphoric acid H3PO4. The phosphate or orthophosphate ion [PO. 4]3−. is derived from phosphoric acid by the removal of three protons H+.
Hypophosphoric acid is a mineral acid with the formula H 4 P 2 O 6, with phosphorus in a formal oxidation state of +4. In the solid state it is present as the dihydrate, H 4 P 2 O 6 ·2H 2 O. In hypophosphoric acid the phosphorus atoms are identical and joined directly with a P−P bond. Isohypophosphoric acid is a structural isomer of ...
Phosphorous acid (or phosphonic acid) is the compound described by the formula H3PO3. This acid is diprotic (readily ionizes two protons), not triprotic as might be suggested by this formula. Phosphorous acid is an intermediate in the preparation of other phosphorus compounds.
Phosphatidic acid. Phosphatidic acids are anionic phospholipids important to cell signaling and direct activation of lipid-gated ion channels. Hydrolysis of phosphatidic acid gives rise to one molecule each of glycerol and phosphoric acid and two molecules of fatty acids. They constitute about 0.25% of phospholipids in the bilayer.
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 structure of H 3 PO 5, displaying the intramolecular hydrogen bond. Peroxymonophosphoric acid is a colorless, viscous liquid. It is stabilized by an intramolecular hydrogen bond. [6] The compound is a triprotic acid with acid dissociation constants pK a1 = 1.1, pK a2 = 5.5 and pK a3 = 12.8. In aqueous solutions it slowly undergoes ...
