Chemical formula of bleaching powder is _________.

CaOCl₂

The correct answer is option 1. \(CaOCl_2\)

Bleaching powder, also known as calcium oxychloride, has the chemical formula CaOCl2. Let's break down this formula:

1. \(Ca:\) Calcium

2. \(O:\) Oxygen

3. \(Cl:\) Chlorine

The combination of these elements results in \(CaOCl_2\). Bleaching powder is a white powder that is widely used for bleaching and disinfection purposes. It is commonly used in the textile industry for bleaching fabrics and in water treatment for disinfecting and removing impurities.

The chemical formula indicates that one molecule of bleaching powder is composed of one calcium atom (Ca), one oxygen atom (O), and two chlorine atoms (Cl). The arrangement of these atoms in the chemical structure of bleaching powder gives it its specific properties and applications.
