Paper Details

Phosphorous acid, H3PO3, has the structure (HO)2PHO, in which one H atom is bonded to the P atom, and two H atoms are bonded to O atoms. For each bond to an H atom, decide whether it is polar or nonpolar. Assume that only polar-bonded H atoms are acidic. Write the balanced equation for the complete neutralization of phosphorous acid with sodium hydroxide. A 200.0-mL sample of H3PO3 requires 22.50 mL of 0.1250 M NaOH for complete neutralization. What is the molarity of the H3PO3 solution?
