The reaction of white phosphorus on boiling with alkali in the inert atmosphere resulted in the formation of the product 'A'.

\mathrm{P}_{4}+3 \mathrm{OH}^{-}+3 \mathrm{H}_{2} \mathrm{O} \rightarrow \mathrm{PH}_{3}+\underset{\text { (A) }}{3 \mathrm{H}_{2} \mathrm{PO}_{2}^{-}}

The reaction 1 mol of 'A' with an excess of AgNO3 in an aqueous medium gives 4 moles of Ag.

\underset{1 \text { mole }}{\mathrm{H}_{2} \mathrm{PO}_{2}^{-}}+\underset{\text { excess }}{4 \mathrm{Ag}^{+}}+2 \mathrm{H}_{2} \mathrm{O} \rightarrow \underset{4 \text { mole }}{4 \mathrm{Ag}\ +\ } \mathrm{H}_{3} \mathrm{PO}_{4}+3 \mathrm{H}^{+}
