Detailed Solution

The given statement is false.
Concept: Actually, bleaching powder is a concoction of many chemicals. Calcium hypochlorite, sodium hypochlorite, hydrogen peroxide, and sodium hydroxide are the primary substances involved. Usually, it's used to get paint or stains out of cloth. Since it is highly reactive, handling should be done with caution. Its texture is powdery.
Bleaching powder is soluble in cold water. When we add water in bleaching powder the solution turns milky due to the formation of calcium carbonate.

Its most notable characteristic is a strong chlorine odour. It is water soluble. It does not create a clear solution since it contains certain contaminants. So, the given statement is false.
The correction here should be, bleaching powder is soluble in cold water.
Hence, the correct answer is option 2.
