Which ion forms a white precipitate with silver nitrate?

Explanation:
Silver nitrate reacts with chloride ions to form silver chloride, which is a white, insoluble solid. That white precipitate is a classic clue that chloride is present. Bromide and iodide would give colored precipitates (cream for bromide, yellow for iodide) due to the different colors of AgBr and AgI, while sulfate tends to stay dissolved under common test conditions, so it doesn’t produce a noticeable precipitate with silver nitrate. So the white solid specifically indicates chloride.
