The volume of $1 \mathrm{N} \mathrm{KMnO}_{4}$ required to reach equivalence point in the titration with 0.01 mole of ferrous oxalate dissolved in dilute $\mathrm{H}_{2} \mathrm{SO}_{4}$ is
(a)$3 \mathrm{cm}^{2}$
(b)$30 \mathrm{cm}^{3}$
(c)$10 \mathrm{cm}^{3}$
(d)$20 \mathrm{cm}^{3}$
Answer
Answer: B ✓ checked by 4AB · confidence high
Explanation
FeC₂O₄ supplies 3 electrons (Fe²⁺ → Fe³⁺, C₂O₄²⁻ → 2CO₂): 0.03 eq → 30 cm³ of 1 N KMnO₄ (b).
