Phosphorous acid is the compound described by the formula H3PO3. This acidis diprotic (readily ionizes two protons), not triprotic as might be suggested by this 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 phosphonic acids.
"Phosphonic acid" redirects here. For Phosphonic acids, see Phosphonate.
Not to be confused with Phosphoric acid or Phosphorus acid.
