Question

The reaction of white phosphorus with aqueous NaOH gives phosphine along with another phosphorus containing compound. The reaction type; the oxidation state of phosphorus in phosphine and the other product are respectively, Redox reaction; +3 and +5, Redox reaction; -3 and – 5, Disproportionation reaction; - 3 and +3, Disproportionation reaction; - 3 and +1

MARKS App · Accepted Answer

The reaction of white phosphorus with aqueous NaOH gives phosphine along with sodium hydrogen phosphite. It is Disproportionation reaction in which oxidation number of phosphorus is changing from 0 to -3 and +3 as follows P 4 0 + NaOH aq → PH 3 − 3 + Na 2 HPO 3 + 3
