**Passage 8:** A mixture of and requires mL of for titration in acidic medium. The same amount of mi — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

**Step 1:** Let moles be $x$ and $y$. <br>**Step 2:** Acid-Base: $Fe_2(C_2O_4)_3$ is not acidic, but the question assumes hydrolysis or specific acidic units. Usually, only the oxalate moiety reacts with $KMnO_4$. <br>**Step 3:** $n$-factor $FeC_2O_4 = 3$; $n$-factor $Fe_2(C_2O_4)_3 = 6$. <br>**Step 4:** $3x + 6y = 50 \times 0.1 \times 5 = 25$ meq. (Solving system yields $y=0.0005$).
