Final answer:
To distinguish silver chloride, bromide, and iodide, you can use chlorine water and carbon tetrachloride. Silver chloride is a white precipitate, while silver bromide and silver iodide precipitates are both pale yellow.
Step-by-step explanation:
To distinguish silver chloride (AgCl), silver bromide (AgBr), and silver iodide (AgI), we can use chlorine water (Cl2) and carbon tetrachloride (CCl4). When reacted with silver nitrate (AgNO3), all three compounds form precipitates. Silver chloride is a white precipitate, while silver bromide and silver iodide precipitates are both pale yellow.
To determine whether the precipitate is a bromide or an iodide, we can add chlorine water. If the precipitate dissolves, it is a bromide. If it remains unchanged, it is an iodide. Carbon tetrachloride can also be used. If the precipitate dissolves, it is a chloride. If it remains unchanged, it is either a bromide or an iodide.
