Question
n the test to distinguish halide ions, the reagents commonly used are----------------A. AgNO3(aq) and HNO3(aq)B. BaCl2(aq) and HCl(aq)C. AgNO3(aq) and NH3(aq)D. AgNO3(aq) and BaCl2(aq)
Solution
The reagents commonly used to distinguish halide ions are A. AgNO3(aq) and HNO3(aq).
Here's why:
The test for halide ions often involves using a silver nitrate solution. The halide ions will react with Ag+ ions from the AgNO3 to form a precipitate. The color of the precipitate can then be used to identify which halide ion is present: chloride ions form a white precipitate, bromide ions form a cream precipitate, and iodide ions form a yellow precipitate.
The HNO3 is used to remove any other ions that might interfere with the test. It does this by reacting with carbonate ions, for example, to form carbon dioxide and water, thereby removing the carbonate ions from the solution.
