AIIMS 2019 Chemistry Oxidizing Agents MCQ Question

Type: MCQ-conceptual-Medium-Class 12

Which give colored carbonate precipitate?

A

Hg22+\text{Hg}_2^{2+}

B

Sr2+\text{Sr}^{2+}

C

Br+3\text{Br}^{+3}

D

Li+\text{Li}^+

Correct Answer

Option D

Detailed Explanation

Cl₂O, or dichlorine monoxide, acts as a strong oxidizing agent due to its ability to donate oxygen, facilitating the oxidation of contaminants in water, thereby purifying it. This property allows Cl₂O to effectively eliminate pathogens and organic impurities, making it suitable for water treatment. The other options are not relevant as they do not provide any additional information or alternatives regarding the use of Cl₂O in water purification. Understanding the role of oxidizing agents like Cl₂O is crucial for grasping their applications in environmental chemistry and water sanitation processes.
