Question
- A. Flame test
- B. Sodium hydroxide precipitate test
- C. Silver nitrate test
- D. Barium chloride test
Answer
The correct answer is Silver nitrate test. It matches halide ion because the evidence is silver nitrate after acidifying and the expected result is precipitate colour.
Explanation
The correct option is Silver nitrate test. This is correct because silver nitrate after acidifying is the evidence expected for halide ion, and precipitate colour is the result that supports the conclusion. Other options are weaker when they confuse gas tests, flame colours, ion-test precipitates, chromatography evidence, or pure-substance/formulation wording.
Common mistake
Bromide Precipitate Confusion
Students often confuse the precipitate produced by bromide ions with that of chloride ions, thinking both produce a white precipitate.
Remember that bromide ions produce a cream precipitate, while chloride ions produce a white precipitate. Visual aids or color charts can help reinforce this distinction.
