Question

Why bleaching powder doesn't dissolve in water completely?​

Answer 1

It does disolve

Step-by-step explanation:

It depends on how much bleaching powder you're trying to dissolve in water

Answer 2

bleaching powder is actually a mixture of calcium chloride, calcium hydroxide and calcium hypochlorite. hence it is not a single salt. It is not completely soluble in water as it composed of heavy calcium salts, which are known to be insoluble in water.
