Sodium nitrite with hydrochloric acid gives water along with two nitrogen oxides. They are

  1. A \(\mathrm{NO}, \mathrm{NO}_2\)
  2. B \(\mathrm{NO}_2, \mathrm{~N}_2 \mathrm{O}_3\)
  3. C \(\mathrm{NO}_2, \mathrm{~N}_2 \mathrm{O}\)
  4. D \(\mathrm{NO}, \mathrm{N}_2 \mathrm{O}_5\)
Verified Solution

Answer & Solution

Correct Answer

(A) \(\mathrm{NO}, \mathrm{NO}_2\)

Step-by-step Solution

Detailed explanation

\(2 \mathrm{NaNO}_2+2 \mathrm{HCl} \rightarrow 2 \mathrm{NaCl}+\mathrm{NO}_2+\mathrm{NO}+\mathrm{H}_2 \mathrm{O}\) In case of nitrogen, all oxidation states from +1 to +4 tend to disproportionate in acid solution.
