What are the two oxidation states of nitrogen in nh4no2?
THIS IS THE BEST ANSWER 👇
The oxidation state is N in (NH₄) (-3).
The oxidation state is N in (NO₂) (+3).
Explanation:
NH₄NO₂ is disconnected according to the equation:
NH₄NO₂ → NH₄⁺ + NO₂⁻.
We can calculate the oxidation state:
NH₄⁺:
The total oxidation state is NH₄⁺ (+1).
The oxidation state of H (+1) is known.
State Oxidation state N + 4 (oxidation state H) = +1.
State Oxidation state N + 4 (+1) = +1.
State Oxidation state N = +1 – 4 = -3.
NO:
The total oxidation state is NO₂⁻ (-1).
(-2) is known to be the oxidation state of O.
State Oxidation state N + 2 (oxidation state O) = -1.
State Oxidation state N + 2 (-2) = -1.
State Oxidation state N – 4 = -1.
State Oxidation state N = -1 + 4 = +3.
