Reacts explosively with mercury(II) oxide [Mellor, 1940, Vol. It is a colorless low-melting compound, which is soluble in water, dioxane, and alcohols. the oxidation state of phosphorous in $\ce{H3PO2}$ is $+5$, as hydrogen and oxygen both are more electronegative than phosphorous, and phosphorous can never increase its oxidation state to more than $+5$, so how can it be a strong reducing agent? Hypophosphorous acid is the phosphorus oxo acid or hydroxy phosphine oxide, with monobasic character. Inorganic chemists refer to the free acid by this name (also as "HPA"), or the acceptable name of phosphinic acid. Chemsrc provides Hypophosphorous acid(CAS#:6303-21-5) MSDS, density, melting point, boiling point, structure, formula, molecular weight etc. The structural diversity and synthesis of acidic ionic liquids are discussed in the introduction sections of this review.
