Question

Name the substance that on treatment with Chlorine yields bleaching powder.

Answer 1

Bleaching powder:

1. Calcium hypochlorite is the other name for bleaching powder. ${\mathrm{CaOCl}}_2$ is its chemical formula.
2. It is an inorganic chemical present in a variety of commercial items. In the home, bleaching powder is used to kill bacteria in the water. In industry, it is even utilized as an oxidizing agent.
3. When chlorine is passed over slaked lime$\mathrm{Ca}{\left(\mathrm{OH}\right)}_2$, it is quickly absorbed, yielding bleaching powder or a lime chloride. $\underset{\mathrm{Calcium}\mathrm{hydroxide}}{\mathrm{Ca}{\left(\mathrm{OH}\right)}_2\left(\mathrm{s}\right)}+\underset{\mathrm{Chlorine}}{{\mathrm{Cl}}_2\left(\mathrm{g}\right)}\to \underset{\mathrm{Hypochlorite}}{{\mathrm{CaOCl}}_2\left(\mathrm{s}\right)}+\underset{\mathrm{Water}}{{\mathrm{H}}_2\mathrm{O}\left(\mathrm{l}\right)}$
4. In general, calcium hydroxide is made by combining calcium oxide (commonly known as quicklime) with water.
5. In its solid-state, it is a white inorganic substance with a powdery appearance.
6. In acids and glycerol, It is quite soluble, but it is only slightly soluble in water.

Therefore, Calcium hydroxide on treatment with chlorine yields bleaching powder.
