Hey guys, I'm having trouble getting the right answer for question 14.5d. A little clarification would be helpful. Thanks!
P4=H2PO2- + PH3 under basic condition.

can you maybe be a bit more specific about your question? Are you asking for how this reaction occurs or how the process is to get the products? I think the main idea here is that P4 is acting as both the oxidizing AND the reducing agent. Was that the part that was confusing?

In this problem, P4 is both the reducing and oxidizing agent. Therefore, you can start by separating and balancing both half-reactions. Remember, you start with P4 in both reactions. After balancing them you can combine them in order to get the final equation.
