THE structure of the hypophosphate ion has been the subject of speculation and controversy since hypophosphoric acid was discovered by Salzer 1 in 1877. The electronic structure of hypophosphorous acid is such that it has only one hydrogen atom bound to oxygen, and it is thus a monoprotic oxyacid. It is a phosphorus oxoacid or hydroxy phosphine oxide with a monobasic character (oxide of PH3 which contains OH-). 2H 2 O. Additional Metadata. Hypophosphorous acid solution 50 wt. 2: Phosphorous Acid. Pure hypophosphorous acid forms white crystals that melt at 26.5° C.

For example, following data is given regarding the structure of pyrophosphorus acid in my textbook, which is not consistent with the number of oxygen atoms. Hypophosphoric Acid (H 4 P 2 O 6) It is set up by controlled oxidation of red phosphorus with sodium chlorite arrangement when disodium salt of the hypophosphoric acid is obtained it is passed through cation exchanger to yield hypophosphoric acid. The structure of rhombohedral (R\overline{3}) iron(III) tris­[di­hydrogen­phosphate(I)] or iron(III) hypophosphite, Fe(H2PO2)3, has been determined by single-crystal X-ray diffraction. Hypophosphorous acid, also known as phosphinic acid, HPA, hydroxy(oxo)-λ5-phosphane, oxo-λ5-phosphanol and oxo-λ5-phosphinous acid, is an inorganic compound with the formula H3PO2.
