Which of the following chemical samples will independently consume exactly 600 mL of a 0.1 M solutio — Redox Reactions and Volumetric Analysis Chemistry Question

💡 Solution & Explanation

Equivalents of $KMnO_4$ = $0.1 \times 0.600 \times 5 = 0.3$ eq. A: $0.10 \times 3 (n\text{-factor}) = 0.3$ eq. B: $0.15 \times 2 (n\text{-factor}) = 0.3$ eq. C: $0.30 \times 1 (n\text{-factor}) = 0.3$ eq. D: $As_2S_3$ oxidizes to $AsO_4^{3-}$ and $SO_4^{2-}$ (n-factor = 28). $0.05 \times 28 = 1.4$ eq (Incorrect).
