Identify the correct pairs in which the chemical substance given is correctly matched with its use \begin{array}{ll} Chemical substance & use \ (A) \mathrm{Cl}_2 & Preparation of phosgene \ (B) \mathrm{I}_2 \mathrm{O}_5 & estimation of \mathrm{CO} \ (C) \mathrm{O}_3 & disinfectant \end{array}
- A A,B,C
- B A,B only
- C B,C only
- D A,C only
Answer & Solution
Correct Answer
(A) A,B,C
Step-by-step Solution
Detailed explanation
\(\mathrm{CO}+\mathrm{Cl}_2 \rightarrow \mathrm{COCl}_2\) phosgene \(\mathrm{I}_2 \mathrm{O}_5\) is a good oxidizing agent that is used for the estimation of \(\mathrm{CO}\). \(\mathrm{O}_3\) is used as a disinfectant, bleaching and various other purposes.
