In the thermal comproportionation reaction , what is the magnitude of the change in the oxidation nu — Redox Reactions and Volumetric Analysis Chemistry Question
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?
Answer: 3
💡 Solution & Explanation
In the $NH_4^+$ ion, nitrogen has an oxidation state of -3 (since H is +1). In the product $N_2$, nitrogen is in its elemental state, meaning its oxidation state is 0. The magnitude of the change is $ | 0 - (-3) | = 3$.
