In chemistry, meta is a prefix, used for systematic names in IUPAC nomenclature. It has several meanings.In organic chemistry, meta indicates the positions of substituents in aromatic cyclic compounds. The substituents have the 1,3-positions, for example in resorcinol. Meta may also denote the dehydrated form of an acid, salt or organic derivative in a series. For example: metabisulfite: 2 bisulfite → 1 metabisulfite + H2O metaphosphoric acid: 3 orthophosphoric acid → 1 trimetaphosphoric acid + 3 H2O Meta-antimonic acid, the dehydrated form of antimonic acid, is HSbO3.
