What is the mass of oxalic acid, H₂C₂O₄, which can be oxidized to CO₂ by 100 ml of MnO₄⁻ solution, 10 ml of which is capable of oxidizing 50 ml of 1.00 N I⁻ to I₂?
Options:
Answer:
D
Solution:
10 ml of the MnO₄⁻ solution = 50 ml x 1.00 N = 50 meq, so the permanganate solution is 5 N. 100 ml then contains 500 meq. Oxalic acid (n = 2, eq. mass = 45): mass = 500 x 45 mg = 22.5 g, option (d).
