When KI is added to acidified solution of solution of sodium nitrite :

NO gas is liberated and `I_(2)` is set free

`N_(2)` gas is liberated and HI is produced

`N_(2)O` gas is liberated and `I_(2)` is set free

`N_(2)` gas is liberated and HOI is produced

Text Solution

Verified by Experts

The correct Answer is:

`NO_(2)^(-) +2I^(-)+4CH_(3)CO OH to I_(2)+2NO uarr +4 CH_(3)CO O^(-)+2H_(2)O`
