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

A

(a)23.48

B

(b)46.96

C

(c )53.78

D

(d)71.00

Text Solution

Verified by Experts

The correct Answer is:
C
`underset(2(36+1+31+64)=264)(2(NH_(4))_(2)HPO_(4))-= underset(62+80=142)(P_(2)O_(5))`
`% of P_(2)O_(5)=("wt. of" P_(2)O_(5))/("wt. of salt")xx100`
`=142/264xx100=53.78%`

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)
