NEET Chemistry (general) MCQ Question
Which of the following statements correctly describe the tests for detecting specific ions in qualitative analysis?
The chromyl chloride test confirms the presence of chloride ions by producing a yellow precipitate of lead chromate.
The barium chloride test for sulfite ions produces a white precipitate of barium sulfite upon reaction with sodium sulfite.
The sodium nitroprusside test confirms the presence of carbonate ions by forming a purple complex.
The reaction of sulfite ions with warm dilute sulfuric acid produces sulfur dioxide gas, which can be detected by its suffocating smell.
Correct Answer
Detailed Explanation
The chromyl chloride test confirms the presence of chloride ions by forming a yellow precipitate of lead chromate when acidified. Additionally, the other options contain misconceptions about the reactions related to specific ions.
