Question
- A. Chloride
- B. Bromide
- C. Iodide
- D. Sulfate
Answer
The correct answer is Chloride. It matches halide ion because the evidence is silver nitrate after acidifying and the expected result is precipitate colour.
Explanation
The correct option is Chloride. Use this as an exam check: if the observation is not precipitate colour, the conclusion about halide ion is not properly supported. 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.
