Used in foods as an acidulant for drinks and candies, pH control agent, buffering agent, flavour enhancer, flavouring agent, sequestrant, stabiliser and thickener, and synergist Phosphoric acid, also known as orthophosphoric acid or phosphoric(V) acid, is a mineral (inorganic) acid having the chemical formula H3PO4. Orthophosphoric acid molecules can combine with themselves to form a variety of compounds which are also referred to as phosphoric acids, but in a more general way. The term phosphoric acid can also refer to a chemical or reagent consisting of phosphoric acids, usually orthophosphoric acid. (Wikipedia) The phosphate ion is a polyatomic ion with the empirical formula PO4H and a molecular mass of 94.97 daltons; it consists of one central phosphorus atom surrounded by four identical oxygen atoms in a tetrahedral arrangement. It is a hypervalent molecule (the phosphorus atom has 10 electrons in its valence shell). A phosphate, in inorganic chemistry, is a salt of phosphoric acid. Phosphates are also important in biochemistry and biogeochemistry. In agriculture phosphate refers to one of the three primary plant nutrients, and it is a component of fertilizers. In ecological terms, because of its important role in biological systems, phosphate is a highly sought after resource. Consequently, it is often a limiting reagent in environments, and its availability may govern the rate of growth of organisms. Addition of high levels of phosphate to environments and to micro-environments in which it is typically rare can have significant ecological consequences. In the context of pollution, phosphates are a principal component of total dissolved solids, a major indicator of water quality. [HMDB] |
