A solution of colourless salt H on boiling with axcess `NaOH` produces a non-flammable gas. The gas evolution ceases after sometime. Upon addition of Zn dust to the same solution, the gas evolution restarts. The colourless salt(s) H is (are)

A

`NH_(4)NO_(3)`

B

`NH_(4)NO_(2)`

C

`NH_(4)Cl`

D

`(NH_(4))_(2)SO_(4)`

Text Solution

Verified by Experts

The correct Answer is:
A, B
The colourless salt H may be either `NH_(4)NO_(3)orNH_(4)NO_(2)` and the non-inflammable gas is `NH_(3)`
(a) `NH_(4)NO_(3)+NaOHoverset(Delta)toNH_(3)+NaNO_(3)+H_(2)O`
Non-inflammable gas
`4Zn+7NaOH+NaNO_(3)overset(Delta)to4Na_(2)ZnO_(2)+NH_(3)+2H_(2)O`
Sod. zincate Gas evolution restarts
(b) `NH_(4)NO_(2)+NaOHoverset(Delta)toNH_(3)+NaNO_(2)+H_(2)O`
`3Zn+5NaOH+NaNO_(2)overset(Delta)to3Na_(2)ZnO_(2)+NH_(3)+H_(2)O`
