Question

What colour precipitate is produced when bromide ions are tested with acidified silver nitrate solution?

Answer

A high-scoring answer should explain recall that bromide ions produce a cream precipitate. Use method first, observation second, conclusion last: name the relevant test or measurement, state the observation, and then connect the result to Halide ions.

Explanation

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. A complete answer should use the approved objective wording, include the relevant evidence, and avoid unsupported identification claims.

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.
