Q76 / 180 · AIIMS 2011 · Chemistry
Predict the product of reaction of $\mathrm{I}_2$ with $\mathrm{H}_2 \mathrm{O}_2$ in basic medium.
- Correct answerA$\mathrm{I}^{-}$
- B$\mathrm{I}_2 \mathrm{O}_3$
- C$\mathrm{IO}_3^{-}$
- D$\mathrm{I}_3^{-}$
Solution
$\mathrm{I}_{2(s)}+\mathrm{H}_2 \mathrm{O}_{2(a q)}+2 \mathrm{OH}^{-}(a q) \longrightarrow$
$$
2 \mathrm{I}_{(a q)}^{-}+2 \mathrm{H}_2 \mathrm{O}_{(l)}+\mathrm{O}_{2(g)}
$$
Hence, the correct answer is option: 'A'.
