Which of the following is used in the estimation of carbon monoxide?
Which of the following is used in the estimation of carbon monoxide?
$\mathrm{I}_2 \mathrm{O}_4$
$\mathrm{BrO}_3$
$\mathrm{Cl}_2 \mathrm{O}_7$
$\mathrm{I}_2 \mathrm{O}_5$
Solution
Carbon monoxide is estimated using $\mathrm{I}_2 \mathrm{O}_5$ as per the following reaction:
$
\mathrm{I}_2 \mathrm{O}_5+5 \mathrm{CO} \longrightarrow \underset{\text { violet }}{\mathrm{I}_2}+5 \mathrm{CO}_2
$
