Which of the following conditions must be strictly met for a back-titration procedure to be experime — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Back-titration involves adding a precise excess of reagent B to analyte A, then titrating the unreacted B with C. This works only if A completely consumes its share of B (Statement A), C perfectly measures the remaining B (Statement B), and the exact starting amount of B is known (Statement D). Crucially, the products of the A+B reaction must *not* react with C (Statement C is false), otherwise C measures the product instead of the excess B.
