What happens when white phosphorus is heated with concentrated NaOH solution in an inert atomosphere of `CO_(2)` ?

Text Solution

Verified by Experts

White phosphorus when heated with concentrated `NaOH` forms phosphine, `PH_(3)` and sodium hypophosphite, `NaH_(2)PI_(2)`.
`P_(4)+underset("conc.")(3NaOH)+3H_(2)Ooverset("hot")rarr PH_(3)+3NaH_(2)PO_(2)`
