A sample of pure KHC₂O₄·H₂C₂O₄·2H₂O requires 30 mol of NaOH for titration. How many moles of KMnO₄ will the same sample react with, in acid medium?
Answer:
8.00
Solution:
Each formula unit has 3 ionizable H⁺, so 30 mol NaOH ⇒ 10 mol salt. Each unit carries 2 oxalate groups, so C₂O₄ = 20 mol. In acid: 2KMnO₄ : 5C₂O₄²⁻, so KMnO₄ = 2/5 × 20 = 8 mol. Ans: 8.
