Asserarion: Phosphine is prepared in an inert atmoshphere of `CO_(2)` and `H_(2)`.
Reason: Phosphine is highly inflammable in air.

Explain the Phosphine is prepared in an inert atmosphere of CO_(2) or H_(2) .

(a) What is the role of phosphorous pentoxide in the preparation of N_2 O_5 ? (b) Phosphine is prepared in an inert atmosphere of CO_2 . Why ? ( c) Red phosphorous is used for making matches. Why ?

Phosphine prepared by the action of caustic soda on white phophorus is highly inflammable because it contains small amounts of :

White phosphorus when heated with conc.NaOH solution in an inert atmosphere of CO_(2) , forms phosphine and a sodium salt of oxoacid of phosphorus X .The oxidation state of phosphorus in X ' is

White phosphorus on reaction with concentrated NaOH solution in an inert atmosphere of CO_(2) , gives phosphine and compound (X). (X) on acidification with HCl gives compound (Y). The basicity of compound (Y) is:
