The pure acid can be obtained by extraction of its aqueous solution by diethyl ether, (C2H5)2O. Pure hypophosphorous acid forms white crystals that melt at 26.5 °C (79.7 °F). 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.
What is formula for hypophosphorous acid?
Hypophosphorous acid (HPA), or phosphinic acid, is a phosphorus oxyacid and a powerful reducing agent with molecular formula H3PO2. It is a colorless low-melting compound, which is soluble in water, dioxane, and alcohols.
How do you test for Hypophosphorous acids?
Assay— Pour about 7mLof Hypophosphorous Acid into a tared,glass-stoppered flask,and weigh accurately. Dilute with about 25mLof water,add phenolphthalein TS,and titrate with 1Nsodium hydroxide VS. Each mLof 1Nsodium hydroxide is equivalent to 66.00mg of H3PO2.
