Question

In the following reaction
$X e F_{2} + {B r O_{3}}^{-} + H_{2} O ⟶ X e + {B r O_{4}}^{-} + 2 H F$

$e q u i v a l e n t m a s s o f {B r O_{3}}^{-} = \frac{m o l a r m a s s}{. . . . . . . . . .}$

Solution

In the following reaction:

$X e F_{2} + {B r O_{3}}^{-} + H_{2} O ⟶ X e + {B r O_{4}}^{-} + 2 H F$

$e q u i v a l e n t m a s s o f B r O_{3}^{-} = \frac{m o l a r m a s s}{2}$ .

The oxidation number of Br changes form +5 to +7. Hence, the net change in the oxidation number is 2.
