Question

In the thermal comproportionation reaction $NH_4NO_2 \xrightarrow{\Delta} N_2 + 2H_2O$, what is the magnitude of the change in the oxidation number of the nitrogen atom originating from the ammonium ($NH_4^+$) ion?

Prashant Kotian · Accepted Answer

Correct answer: 3. In the ion, nitrogen has an oxidation state of -3 (since H is +1). In the product , nitrogen is in its elemental state, meaning its oxidation state is 0. The magnitude of the change is .
