Question

Write balanced chemical equation for the following reactions:
a) Iodine ions can be oxidized by ozone in acidic medium.

Answer 1

$KI+O_3+H_{2}O⟶\frac{1}{2}{I}_2+O_2+KOH$

or, $I^{-}+O_3+H^{+}⟶\frac{1}{2}{I}_2+O_2+O{H}^{-}$

In the given reaction, the iodine ion is oxidized to form iodine along with KOH as a product.
