Complete the equation and adjust the coefficients using the P + KOH electronic balance method.

The reaction takes place between potassium hydroxide and phosphorus. But in order for the reaction to go fully, we also need to add water. As a result of the reaction, phosphine and a complex inorganic compound sodium dihydrogen phosphate are formed. The chemical equation for the reaction is as follows:

4 P + 3 KOH + 3 H2O = PH3 + 3 NaH2PO2

Makes up the redox equation:

P + + 3e = P 3- 1 oxidizer,

P + – 1e = P 3+ 3 reducing agent.
