Vedclass · Answer

(B) The given reaction is the laboratory method for the preparation of phosphine $(PH_3)$ gas.The balanced chemical equation is:$P_4 + 3NaOH + 3H_2O 	o PH_3 + 3NaH_2PO_2$In this reaction,white phosphorus undergoes a disproportionation reaction where it is simultaneously oxidized and reduced to form phosphine $(PH_3)$ and sodium hypophosphite $(NaH_2PO_2)$.

$P_4 + 3NaOH + 3H_2O \to A + 3NaH_2PO_2$. Here,$A$ is:
