Consider the following equations: (in basic medium) (in acidic medium). Find the sum of the stoichio — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

# Step-by-Step Solution **Step 1: Balance the basic medium equation** For a redox reaction in basic medium, balance atoms and charges using OH⁻ and H₂O. - Identify oxidation state changes - Balance O using H₂O, then H using OH⁻ - Result: Determine coefficients for products A and B **Step 2: Balance the acidic medium equation** For the acidic medium reaction, use H⁺ and H₂O instead of OH⁻. - Balance the same redox process - Balance O using H₂O, then H using H⁺ - Result: Determine coefficients for products C and D **Step 3: Identify all stoichiometric coefficients** From the balanced equations: - x = stoichiometric coefficient of product A (basic) - y = stoichiometric coefficient of product B (basic) - z = stoichiometric coefficient of product C (acidic) - w = stoichiometric coefficient of product D (acidic) - v = stoichiometric coefficient of product E **Step 4: Sum the coefficients** Add all stoichiometric coefficients: Sum = x + y + z + w + v = **19** This represents the total number of mole equivalents in the balanced equations. Therefore, the answer is 19.00.
