general-sciencechemistry
- ABleaching powder is prepared by the action of Chlorine on dry slaked lime [Ca(OH)2]
- BBleaching powder acts as a reducing agent in many chemical industries
- CBleaching powder is also known as chlorinated lime
- DBleaching powder is used for disinfecting drinking water
Explanation
Bleaching powder (chlorinated lime, CaOCl2) is an oxidising agent, not a reducing agent, because of the available chlorine it releases. It is correctly prepared by the action of chlorine on dry slaked lime, is also called chlorinated lime, and is used to disinfect drinking water. Hence statement (B) is the one that is not correct.
