Sodium salt solution + AgNO3 soln. -> Coloured precipitate. If coloured precipitate is soluble in bo — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Step 1: Identify the solid: Barium chromate (BaCrO4↓) is a very stable yellow precipitate with a low solubility product. Step 2: Analyze reaction with acetic acid: Acetic acid (CH3COOH) is a weak acid and does not provide a high enough concentration of protons to convert chromate to dichromate and dissolve the BaCrO4. Step 3: Since no chemical reaction or dissolution takes place, this is classified as no reaction (type D).
