In the redox reaction, $M n O_{4}^{-} + I_{2} + H^{+} ⟶ M n^{2 +} + I O_{3}^{-} + H_{2} O$ , $M n O_{4}^{-}$ and $I_{2}$ would react in the molar ratio of

Options:

Answer:

Solution:

Concepts: Balancing redox reactions, oxidation states, electron transfer.

Solution: Balance the redox reaction by equalizing electron transfer. MnO₄⁻ gains 5e⁻, I₂ loses 10e⁻ (2 x 5e⁻). Thus, 2 MnO₄⁻ react with 1 I₂. Ratio is 2:1.
