Answers
Answer:
Bleaching powder is a pale yellowish powder existing with a strong smell of chlorine. It is soluble in water but due to the presence of impurities, we never observe a clear solution. Its chemical formula
is CaoCl2 with its chemical name as Calcium
hypochlorite.
Bleaching powder is used for bleaching dirty clothes in the laundry, as a bleaching agent for cotton and linen in the textile industry. It is also used as a strong oxidizing agent hence used as an oxidizer in many industries. It is also used as a disinfectant which is used for disinfecting water to make potable
water.
When exposed to air, bleaching powder gives a smell of chlorine. This is because bleaching powder reacts with carbon dioxide from the atmosphere to produce calcium carbonate and chlorine.
