Name the solution that can be used to test for halide ions.
Question
Name the solution that can be used to test for halide ions.
Solution
The solution that can be used to test for halide ions is Silver Nitrate solution (AgNO3). Here are the steps to perform the test:
- Add a few drops of Silver Nitrate solution to the test solution.
- Observe the color of the precipitate formed.
- A white precipitate indicates the presence of Chloride ions (Cl-).
- A cream precipitate indicates the presence of Bromide ions (Br-).
- A yellow precipitate indicates the presence of Iodide ions (I-).
- To confirm the results, add Ammonia solution.
- The white precipitate (Chloride ions) will dissolve in dilute Ammonia to form a colorless solution.
- The cream precipitate (Bromide ions) will dissolve in concentrated Ammonia to form a colorless solution.
- The yellow precipitate (Iodide ions) will not dissolve, even in concentrated Ammonia.
