Hypophosphorous acid $(H_3PO_2)$

Vedclass · Answer

(A) To find the oxidation state of phosphorus $(P)$ in each acid,let the oxidation state be $x$:$1$. Hypophosphorous acid $(H_3PO_2)$: $3(+1) + x + 2(-2) = 0 \implies 3 + x - 4 = 0 \implies x = +1$.$2$. Orthophosphoric acid $(H_3PO_4)$: $3(+1) + x + 4(-2) = 0 \implies 3 + x - 8 = 0 \implies x = +5$.$3$. Pyrophosphoric acid $(H_4P_2O_7)$: $4(+1) + 2x + 7(-2) = 0 \implies 4 + 2x - 14 = 0 \implies 2x = 10 \implies x = +5$.$4$. Metaphosphoric acid $(HPO_3)$: $1(+1) + x + 3(-2) = 0 \implies 1 + x - 6 = 0 \implies x = +5$.Comparing the values,the minimum oxidation state is $+1$,which corresponds to Hypophosphorous acid.

In which of the following oxoacids of phosphorus is the oxidation state of phosphorus the minimum?
