Nitrous acid was disproportionated to form water `HNO_(3)` and X .In another reaction sodium nitrite was reacted with `H_(2)SO_(4)` to form `NaHSO_(4), HNO_(3)` water and Y . What are X and Y respectively?

A

`NO,N_(2)O_(3)`

B

`NO, NO`

C

`N_(2)O,NO_(2)`

D

`NO_(2),N_(2)O_(5)`

Text Solution

Verified by Experts

The correct Answer is:
B
Nitrous acid was disproportionated to form water `HNO_(3)` and NO . In another reaction sodium nitrite was reacted with `H_(2)SO_(4)` to form `NaHSO_(4), HNO_(3)` water and NO.
`3HNO_(2) rarr HNO_(3)+H_(2)O+2NO`
`2NaNO_(2)+H_(2)SO_(4) rarr NaHSO_(4)+HNO_(3)+H_(2)O+NO`
