Question
From the following which base in used for the manufacture of bleaching powder?
- KOH
Hint:
Bleaching powder is made by the reaction of chlorine gas on dry slaked lime.
The correct answer is:
One molecule of bleaching powder contains one calcium ion, chloride ion and one hypochlorite . Hence it is also called calcium chloro hypochlorite. It is a mixed salt.
Bleaching powder is made by the reaction of chlorine gas on dry slaked lime.
Ca(OH)2 + Cl2 
CaOCl2 + H2O
