A. CaOCl2✓ Correct Answer
B. Ca(OH)2
C. CaCO3
D. CaCl2
💡 Solution & Explanation
Bleaching powder has the chemical formula CaOCl2 and is technically known as calcium oxychloride. It is manufactured by the action of chlorine gas on dry slaked lime and is widely used for disinfection in water treatment plants. Unlike calcium carbonate or calcium chloride, bleaching powder acts as a strong oxidizing agent due to the presence of available chlorine.
