The reaction of white phosphorus () with leads to the formation of: — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

The reaction is a classic disproportionation: $P_4 + 3NaOH + 3H_2O \rightarrow PH_3 + 3NaH_2PO_2$. Phosphorus is reduced to phosphine ($PH_3$) and oxidized to sodium hypophosphite ($NaH_2PO_2$).
