Phosphite
Structural formula of phosphite ion
Phosphite (systematic name phosphonate) is an ion. Its chemical formula is HPO2−
3. It contains phosphorus in its +3 oxidation state. Chemical compounds containing the phosphite ion are called phosphites. Phosphites are the salts of phosphorous acid. They are poisonous. They are reducing agents. An example would be sodium phosphite.
