The correct Answer is:
To solve the problem of identifying the possible ions in a salt solution that produces a yellow precipitate when silver nitrate is added, we can follow these steps: ### Step 1: Understand the Reaction When silver nitrate (AgNO₃) is added to a salt solution, it reacts with halide ions (Cl⁻, Br⁻, I⁻) to form precipitates. The color of the precipitate can help identify which halide ion is present. ### Step 2: Identify the Precipitate Colors - **Chloride ions (Cl⁻)**: Form a curdy white precipitate of silver chloride (AgCl). - **Bromide ions (Br⁻)**: Form a yellow precipitate of silver bromide (AgBr). - **Iodide ions (I⁻)**: Also form a yellow precipitate of silver iodide (AgI). - **Fluoride ions (F⁻)**: Do not form a precipitate with silver nitrate. ### Step 3: Analyze the Given Information Since the problem states that a yellow precipitate is obtained, we can conclude that the salt solution must contain either bromide ions (Br⁻) or iodide ions (I⁻). ### Step 4: Conclusion Therefore, if a yellow precipitate is obtained upon the addition of silver nitrate to a salt solution, the salt may contain either bromide ions (Br⁻) or iodide ions (I⁻). ### Final Answer The salt may contain bromide ions (Br⁻) or iodide ions (I⁻). ---
