Q
Q: Which reagent is commonly used in the qualitative analysis of halides to form a precipitate?
Solution: Silver nitrate is used to test for halides, forming a precipitate of silver halide when halide ions are present.
Steps: 6
Step 1: Understand what halides are. Halides are compounds that contain halogen elements like chlorine, bromine, and iodine.
Step 2: Know that we want to test for the presence of halides in a solution.
Step 3: Identify the reagent used for this test. The common reagent is silver nitrate (AgNO3).
Step 4: When silver nitrate is added to a solution containing halide ions, a chemical reaction occurs.
Step 5: This reaction produces a solid that is called a precipitate. The precipitate formed is silver halide (AgX), where X is the halide ion (like Cl, Br, or I).
Step 6: The formation of this precipitate indicates that halide ions are present in the solution.
