Question

What observation would indicate the presence of chloride ions when performing a halide test with silver nitrate solution?

Answer

A high-scoring answer should explain explain that the sample is acidified with dilute nitric acid before adding silver nitrate solution. Use evidence before identification: name the relevant test or measurement, state the observation, and then connect the result to Halide ions.

Explanation

The important distinction is that halide ion must be identified from silver nitrate after acidifying; answers that swap in a different test or result do not match Halide ions. A complete answer should use the approved objective wording, include the relevant evidence, and avoid unsupported identification claims.

Common mistake

Acidification Step Mistake

Students often forget to acidify the sample with dilute nitric acid before adding silver nitrate solution, leading to incorrect results.

Always remember to acidify the sample with dilute nitric acid first to ensure accurate identification of halide ions.
