Vedclass · Answer

(C) The dibasic oxoacid of phosphorus is phosphorous acid, $H_3PO_3$.On heating, $H_3PO_3$ undergoes disproportionation reaction as follows:$4H_3PO_3 \rightarrow 3H_3PO_4 + PH_3$Here, the oxidation state of $P$ in $H_3PO_3$ is $+3$.In $H_3PO_4$, the oxidation state of $P$ is $+5$ (oxidation).In $PH_3$, the oxidation state of $P$ is $-3$ (reduction).Thus, the products $A$ and $B$ are $H_3PO_4$ and $PH_3$ respectively.

The dibasic oxoacid of phosphorus on disproportionation gives two products $A$ and $B$. $A$ and $B$ are respectively
