Boric Acid: Properties, Production and Uses
Boric acid is a hydrate of boric oxide, existing as both the trihydrate orthoboric acid, H3BO3 (B2O3·3 H2O), and the monohydrate metaboric acid, HBO2 (B2O3·H2O). Orthoboric acid is the commonly encountered commercial form, often simply referred to as boric acid.
