The correct Answer is:
To prepare phosphine (PH₃), we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Reactants**: - The primary reactants for the preparation of phosphine are white phosphorus (P₄) and sodium hydroxide (NaOH). 2. **Reaction Conditions**: - The reaction takes place in the presence of water. This is important as it facilitates the reaction between white phosphorus and sodium hydroxide. 3. **Write the Chemical Reaction**: - The balanced chemical equation for the reaction is: \[ P_4 + 4 NaOH + 2 H_2O \rightarrow 2 PH_3 + 2 NaH_2PO_2 \] - Here, sodium hypophosphate (NaH₂PO₂) is also produced as a byproduct. 4. **Identify the Product**: - The main product of this reaction is phosphine (PH₃). 5. **Conclusion**: - Therefore, phosphine is prepared by the action of white phosphorus with sodium hydroxide in the presence of water.
