Phosphorous acid (or
phosphonic acid) is the
compound described by the
formula H3PO3. This acid is
diprotic (readily
ionizes two protons), not
triprotic as might...
- acid. P4O6 + 6 H2O → 4
H3PO3 It
reacts with
hydrogen chloride to form
H3PO3 and
phosphorus trichloride. P4O6 + 6 HCl → 2
H3PO3 + 2 PCl3 With chlorine...
- ([HPO2(OH)]−).
These anions are the
conjugate bases of
phosphorous acid (
H3PO3). The
corresponding salts, e.g.
sodium phosphite (Na2HPO3) are reducing...
- salts. Most
processes begin with
phosphorous acid (aka
phosphonic acid,
H3PO3),
exploiting its
reactive P−H bond.
Phosphonic acid can be
alkylated via...
