BaSO4↓ + dil. HCl(Excess) -> No reaction — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Step 1: Identify the solid: Barium sulfate (BaSO4↓) is an extremely insoluble precipitate. Step 2: Analyze the reactivity with acid: Sulfuric acid is a strong acid, meaning its conjugate base (sulfate, SO4^2-) is extremely weak and cannot be protonated by dilute HCl to shift the solubility equilibrium of BaSO4. Step 3: Since no chemical reaction or dissolution occurs, this is classified as no reaction (type D).
