Bleaching powder contains

A. Nitrogen
B. Iodine
C. Chlorine
D. Bromine

Check Answer

The correct answer is C. Chlorine.
Bleaching powder, also known as calcium hypochlorite, is a chemical compound that is widely used as a bleaching agent and disinfectant. It is made by combining calcium hydroxide (slaked lime) with chlorine gas.
When bleaching powder is dissolved in water, it forms hypochlorous acid (HOCl) and calcium chloride (CaCl2). The HOCl is the active ingredient that provides the bleaching action, and it works by oxidizing the pigments in stains, making them less visible.
Bleaching powder is commonly used for bleaching fabrics, paper, and pulp, as well as for disinfecting water and surfaces.
