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.
The single-bonded oxygen atoms that are not shared are completed with acidic hydrogen atoms. The general formula of a phosphoric acid is H n+2−2x P n O 3n+1−x, where n is the number of phosphorus atoms and x is the number of fundamental cycles in the molecule's structure, between 0 and n + 2 / 2 . Pyrophosphate anion. Trimethyl ...
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 ...
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+.
Hypophosphorous acid (HPA), or phosphinic acid, is a phosphorus oxyacid and a powerful reducing agent with molecular formula H 3 PO 2. It is a colorless low-melting compound, which is soluble in water, dioxane and alcohols. The formula for this acid is generally written H 3 PO 2, but a more descriptive presentation is HOP (O)H 2, which ...
Oxyanion. An oxyanion, or oxoanion, is an ion with the generic formula A. xOz−. y (where A represents a chemical element and O represents an oxygen atom). Oxyanions are formed by a large majority of the chemical elements. [1] The formulae of simple oxyanions are determined by the octet rule.
Phosphorus pentoxide crystallizes in at least four forms or polymorphs.The most familiar one, a metastable form [1] (shown in the figure), comprises molecules of P 4 O 10.Weak van der Waals forces hold these molecules together in a hexagonal lattice (However, in spite of the high symmetry of the molecules, the crystal packing is not a close packing [2]).
The dihydrogen phosphate anion consists of a central phosphorus atom surrounded by 2 equivalent oxygen atoms and 2 hydroxy groups in a tetrahedral arrangement. [3] Dihydrogen phosphate can be identified as an anion, an ion with an overall negative charge, with dihydrogen phosphates being a negative 1 charge. [3]
