Vedclass · Answer

(A) The chemical formula of bleaching powder is $CaOCl_2$ or $Ca(OCl)_2 \cdot CaCl_2 \cdot Ca(OH)_2 \cdot H_2O$.It is essentially a mixture of calcium hypochlorite $Ca(OCl)_2$ and calcium chloride $CaCl_2$.The effective component responsible for the bleaching action is the hypochlorite ion $(OCl^-)$,which releases chlorine gas upon reaction with acids or atmospheric $CO_2$.Therefore,the effective component is chlorine.

The effective component of bleaching powder is $.....$ of calcium.
