The number of moles of $K M n O_{4}$ that will be needed to react with one mole of sulphite ion in acidic solution is

Options:

Answer:

Solution:

$2 M n O_{4}^{-} + 6 H^{+} + 5 S O_{3}^{2 -} \to 2 M n^{2 +} + 5 S O_{4}^{2 -} + 3 H_{2} O$
5 mol $S O_{3}^{2 -}$ require $M n O_{4}^{-} = 2$ mol
1 mol $S_{3}^{2 -}$ ions require $M n O_{4}^{-} = \frac{2}{5}$ mol.
