Reagent, \(1 -\)naphthylamine and sulphanilic acid in acetic acid is used for the detection of
- A \(N _{2} O\)
- B \(NO _{3}^{-}\)
- C \(NO\)
- D \(NO _{2}^{-}\)
Answer & Solution
Correct Answer
(D) \(NO _{2}^{-}\)
Step-by-step Solution
Detailed explanation
For detection of \(NO _{2}^{-}\), the following test is used. \(NO _{2}^{-}+ CH _{3} COOH \rightarrow HNO _{2}+ CH _{3} COO ^{-}\)
