Phosphorous acid: Applications, Standards & Products

Phosphorous acid (or phosphonic acid) is the compound described by the formula H3PO3. It is diprotic (readily ionizes two protons), not triprotic as might be suggested by its formula. Phosphorous acid is an intermediate in the preparation of other phosphorus compounds. Organic derivatives of phosphorous acid, compounds with the formula RPO3H2, are called…
