How does bleaching powder eradicate microbes from water?
Bleach liberates chlorine and chlorine is a powerful oxidising agent. Oxidation of the structure of the microbe destroys/kills it.

How do you make bleaching powder?
We know that chlorine is produced during the electrolysis of aqueous sodium chloride. This chlorine gas is used for the manufacture of bleaching powder. Bleaching powder is produced by the action of chlorine on dry slaked lime [Ca(OH)2]. It is represented as CaOCl2. Ca(OH)2+Cl2------CaOCl2+H2O
What happens when chlorine gas is passed through lime water?
When chlorine is passed through dry slaked lime power Ca(OH)2 , bleaching powder is obtained .Slaked lime --- Ca(OH)2 Chlorine --- Cl2The chemical equn :- Ca(OH)2 + Cl2 ------> CaOCl2 + H2OCaOCl2 is bleaching powderThe three properties Of bleaching powder , (CaOCl2) areIt is a yellowish white powder with a strong smell of chlorineIt reacts with carbon dioxide , dil. HCl and di. H2SO4 to form chlorine gas.It is soluble in water but since it is generally contaminated with Ca(OH)2 , it may produce a milky solution
