Question

why does bleaching powder smell strongly of chlorine and does not dissolve completely in water

Answer 1

Bleaching powder smell strongly of chlorine because it reacts with carbon dioxide from the atmosphere to produce chlorine and calcium carbonate. It is not soluble in water because it is made up of insoluble salts.

Answer 2

Heya mate!!!

Bleaching Powder smells strongly of Chlorine when exposed to air because it slowly reacts with atmospheric carbon dioxide to evolve chlorine gas.
The following reaction takes place there:-
CaOCl$₂$(s) + CO$₂$(g) ----> CaCO$₃$(s) + Cl$₂$(g)

And it does not dissolve completely in water as it is composed of heavy calcium salts.
