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+.
This reaction is used for laboratory-scale preparations of PH 3. Phosphorous acid slowly oxidizes in air to phosphoric acid. [5] Both phosphorous acid and its deprotonated forms are good reducing agents, although not necessarily quick to react. They are oxidized to phosphoric acid or its salts. It reduces solutions of noble metal cations to the ...
Phosphorus is an essential mineral for humans listed in the Dietary Reference Intake (DRI). Food-grade phosphoric acid (additive E338 [108]) is used to acidify foods and beverages such as various colas and jams, providing a tangy or sour taste. The phosphoric acid also serves as a preservative. [109]
Organophosphate. In organic chemistry, organophosphates (also known as phosphate esters, or OPEs) are a class of organophosphorus compounds with the general structure O=P (OR)3, a central phosphate molecule with alkyl or aromatic substituents. [1] They can be considered as esters of phosphoric acid. Organophosphates are best known for their use ...
Phosphoric acid fuel cells (PAFC) are a type of fuel cell that uses liquid phosphoric acid as an electrolyte. They were the first fuel cells to be commercialized. Developed in the mid-1960s and field-tested since the 1970s, they have improved significantly in stability, performance, and cost. Such characteristics have made the PAFC a good ...
The original acid phosphate, made by Horsford's chemical company, [3] [5] and was a mixture of calcium, magnesium and potassium phosphate salts with a small amount of phosphoric acid producing a liquid mixture with a pH of around 2 to 3, the same as freshly squeezed lime juice. Horsford used bone ash, which is mostly calcium phosphate. In the ...
