2 overset+5Br (from . BrO 3-5)+10 e- arrow overset0Br 2 ∴ Eq. wt. of KBrO 3=(M/5)

Q. When $B r O_{3}^{-}$ ion reacts with $B r^{-}$ ion in acidic solution $B r_{2}$ is liberated. The equivalent weight of $K B r O_{3}$ in this reaction is

$M /8$

$M /3$

$M /5$

$M /6$

$2 B r + 5$ (from $B r O_{3}^{- 5}) + 10 e^{-} \to B r_{2} 0$

$∴$ Eq. wt. of $K B r O_{3} = \frac{M}{5}$
