What colour precipitate is formed when chloride ions are tested with acidified silver nitrate solution?

A high-scoring answer should explain interpret precipitate colour after adding acidified silver nitrate solution to identify halide ions. Use method first, observation second, conclusion last: name the relevant test or measurement, state the observation, and then connect the result to Halide ions.

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.
