In chemistry, meta is a prefix, used for systematic names in IUPAC nomenclature. It has several meanings. [1]

  • Meta may also denote the dehydrated form of an acid, salt or organic derivative in a series.
For example metabisulfite:
2 bisulfite (HSO3) → 1 metabisulfite S2O52− + H2O
and metaphosphoric acid:
3 orthophosphoric acid H3PO4 → 1 trimetaphosphoric acid (H3P3O9) + 3 H2O.
Meta-antimonic acid, the dehydrated form of antimonic acid (H3SbO4), is HSbO3. [2]
