Which of the following is a mandatory condition for a back-titration procedure to be experimentally — 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. Crucially, the products of the A+B reaction must NOT react with C, otherwise C measures the product instead of the excess B.
