The dibasic oxoacid of phosphorus on disproportionation gives two products A and B. A and B are respectively
Show Hint
Oxoacids of phosphorus with P-H bonds are good reducing agents and tend to undergo disproportionation upon heating. Phosphorous acid (H$_3$PO$_3$, oxidation state +3) disproportionates to phosphoric acid (+5) and phosphine (-3). Hypophosphorous acid (H$_3$PO$_2$, +1) also disproportionates. Phosphoric acid (H$_3$PO$_4$, +5) is in the highest oxidation state and does not disproportionate.
