text:
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 (HSO−3) → 1 metabisulfite (S2O2−5) + H2O
metaphosphoric acid:
3 orthophosphoric acid (H3PO4) → 1
