Infobox references

Metaboric acid is the name for a family of inorganic compounds with the same empirical formula HBO2[2] that differ in their molecular structure. They are colourless water-soluble solids formed by the dehydration or decomposition of boric acid.

Metaboric acid is formally the parent acid of the metaborate anions.
