`NH_(4)CI +Na_(2)HPO_(4)+4Z rarr underset(("sparingly soluble salt"))(A)+ NaCI A overset(Delta)rarr A' +4Z`
`A' overset(Delta)underset("High" T)rarr X+Y uarr +Z`
Compound (Z) is a neutral oxide and turns anhydrous `CuSO_(4)` blue. Gas (Y) is a basic gas which can also be obtained by treating ammonium sulphate with lime water. sequences mentioned above involve balanced reactions.
The compound X is:

A

`NaHPO_(4)`

B

`Na_(3)PO_(3)`

C

`NaPO_(3)`

D

`Na_(3)PO_(4)`

Text Solution

Verified by Experts

The correct Answer is:
C
`Z rarr H_(2)O, A rarr Na(NH_(4))HPO_(4).4H_(2)O, X rarr NaPO_(3)`
`Y rarr NH_(3),A' rarr Na(NH)_(4)HPO_(4)`
