Structure
Category	Flocculant
Description	Sodium perborate (PBS) is a white, odorless, water-soluble chemical compound with the chemical formula NaBO3. It crystallizes as the monohydrate, NaBO3·H₂O, trihydrate, NaBO3·3H₂O and tetrahydrate, NaBO3·4H₂O. The monohydrate and tetrahydrate are the commercially important forms. The elementary structural unit of sodium perborates is a dimer anion B2O4(OH)42−, in which two boron atoms are joined by two peroxo bridges in a chair-shaped 6-membered ring, and the simplistic NaBO3·nH₂O-type formulas are just a convenient way to express the average chemical composition.
