Which reacts with caustic soda, the products are and . This reaction is an examp

Which \( P \) reacts with caustic soda, the products are \( P H_{3} \) and \( N a H_{2} P O_{2} \). This reaction is an example of:

  • A. Hydrolysis
  • B. Reduction
  • C. Disproportionation
  • D. Neutralisation

Step-by-step solution

In the reaction of white phosphorus (P4) with caustic soda (NaOH), phosphorus is both oxidized (from 0 to +1 in NaH2PO2) and reduced (from 0 to -3 in PH3). This simultaneous oxidation and reduction of the same element is characteristic of a disproportionation reaction.
