Chapter 15, Problem 15.130QP
Hypophosphorous acid, H3PO2, and phosphoric acid, H3PO4, have approximately the same acid strengths. From this information, and noting the possibility that one or more hydrogen atoms may be directly bonded to the phosphorus atom, draw the structural formula of hypophosphorous acid. How many grams of sodium hydroxide would be required to completely neutralize 1.00 g of this acid?
