The correct Answer is:
To determine which compound reacts with silver nitrate (AgNO₃) to produce a red precipitate, we will analyze each of the provided options step by step. ### Step 1: Reaction with NAI (Sodium Iodide) - **Reaction**: AgNO₃ + NAI → AgI + NaNO₃ - **Observation**: AgI is formed, which is a yellow precipitate. - **Conclusion**: NAI does not produce a red precipitate. ### Step 2: Reaction with KCL (Potassium Chloride) - **Reaction**: AgNO₃ + KCL → AgCl + KNO₃ - **Observation**: AgCl is formed, which is a curdy white precipitate. - **Conclusion**: KCL does not produce a red precipitate. ### Step 3: Reaction with NANO3 (Sodium Nitrate) - **Reaction**: AgNO₃ + NaNO₃ → No reaction - **Observation**: Both ions are the same, so no precipitate is formed. - **Conclusion**: NANO3 does not produce a red precipitate. ### Step 4: Reaction with NA2CRO4 (Sodium Chromate) - **Reaction**: AgNO₃ + Na₂CrO₄ → Ag₂CrO₄ + 2NaNO₃ - **Observation**: Ag₂CrO₄ is formed, which is a red precipitate. - **Conclusion**: NA₂CrO₄ produces a red precipitate. ### Final Answer The correct answer is **NA₂CrO₄** as it reacts with AgNO₃ to give a red precipitate of Ag₂CrO₄. ---
