The oxidation number of nitrogen atoms in \(\mathrm{NH}_{4} \mathrm{NO}_{3}\) are
- A \(+5\), \(+5\)
- B \(-3,+5\)
- C \(+3,-5\)
- D \(-3,-3\)
Answer & Solution
Correct Answer
(B) \(-3,+5\)
Step-by-step Solution
Detailed explanation
\(\mathrm{NH}_{4} \mathrm{NO}_{3} \longrightarrow \mathrm{NH}_{4}^{+}+\mathrm{NO}_{3}^{-}\)
\(\left(N_{1}\right) \quad\left(N_{2}\right)\)
For oxidation number of \(N_{1} \rightarrow x+4=+1\)
\(x=+1-4=-3\)
So, oxidation state of first nitrogen is \(-3\).
For oxidation state of second nitrogen \(\left(N_{2}\right) \rightarrow\)
\(\begin{aligned}
x-6 &=-1 \\
x &=-1+6=+5
\end{aligned}\)
So, the answer is \(-3\) and \(+5\).
\(\left(N_{1}\right) \quad\left(N_{2}\right)\)
For oxidation number of \(N_{1} \rightarrow x+4=+1\)
\(x=+1-4=-3\)
So, oxidation state of first nitrogen is \(-3\).
For oxidation state of second nitrogen \(\left(N_{2}\right) \rightarrow\)
\(\begin{aligned}
