Testing For Chlorides, Bromides & Iodides

The video tutorial explains how to test for chloride, bromide, and iodide ions in water samples. It covers the preparation of samples by dissolving solids and acidifying them with nitric acid. The addition of aqueous silver nitrate leads to the formation of silver halide precipitates, each with a distinct color: white for chloride, cream for bromide, and yellow for iodide. The video also describes how to distinguish between these precipitates using dilute and concentrated ammonia. Finally, it provides ionic equations for the reactions and concludes with a summary of the key points.

How can you distinguish between silver chloride and silver bromide precipitates?

What happens to silver iodide when treated with dilute or concentrated ammonia?
