Which of the following is used in the estimation of carbon monoxide?
  1. $\mathrm{I}_2 \mathrm{O}_4$
  2. $\mathrm{BrO}_3$
  3. $\mathrm{Cl}_2 \mathrm{O}_7$
  4. $\mathrm{I}_2 \mathrm{O}_5$

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 $
