Calculation of oxidation number of nitrogen in ammonium nitrite NH_(4)NO_(2)

Answer»

Solution :This is an IONIC compound containing `NH_(4)^(+) and NO_(2)^(-)`ions.
The oxidation number of NITROGEN in `NH_(4)^(+)` ion `= -3`
The oxidation number of nitrogen `NO_(2)^(-)` ion `= +3`
Thus, ONE atom of nitrogen in ammonium nitrite is in `-3` oxidation STATE, while the other nitrogen atom is in `+3` oxidation state.
