The percentage of `P_(2)O_(5)` in diammonium hydrogen phosphate is:

A

`77.58`

B

`46.96`

C

`53.78`

D

`23.48`

Text Solution

Verified by Experts

The correct Answer is:
C
`2(NH_(4))_(2)HPO_(4)rarrP_(2)O_(5)`
`:. 2xx132 g(NH_(4))_(2)HPO_(4) "has" 142 g P_(2)O_(5)`
`:. 100 g (NH_(4))_(2) HPO_(4) "has" (142xx100)/(2xx132)gP_(2)O_(5)`
`= 53.78 g P_(2)O_(5)`

P_(2)O_(5) can dehydrate

In a gravimetric determination of P , an aqueous solution of dihydrogen phosphate ion [H_(2)PO_(4)^(-)] is treated with a mixture of ammonium and magnesium ions to precipitate magnesium ammonium phosphate, [Mg(NH_(4))PO_(4).6H_(2)O] . This is heated and decomposed to magnesium pyrophosphate [Mg_(2)P_(2)O_(7)] , which is weighed. A solution of H_(2)PO_(4)^(-) yielded 1.054 g of Mg_(2)P_(2)O_(7) . What weight of NaH_(2)PO_(4) was present originally? (Na=23, H=1, P= 31, O=16,Mg=24)
