Which of the following compound is added to the sodium extract before addition of silver nitrate for testing of halogens?
- A Nitric acid
- B Ammonia
- C Hydrochloric acid
- D Sodium hydroxide
Answer & Solution
Correct Answer
(A) Nitric acid
Step-by-step Solution
Detailed explanation
For testing of halogens, Nitric acid is added to the sodium extract because if \(CN ^{-}\) or \(S ^{2-}\) are present then they will be oxidised and removed before the test of halides.
