NaOCl, also known as sodium hypochlorite, is a chemical compound that is widely used as a disinfectant and bleaching agent. It is a pale greenish-yellow solution with a characteristic odor.

Chemically, NaOCl is formed through the reaction of sodium hydroxide (NaOH) with chlorine gas (Cl2):

NaOH + Cl2 → NaOCl + H2O

The resulting sodium hypochlorite solution is often sold in a diluted form for household or industrial use, typically containing 5-6% of active chlorine. It is important to note that the concentration of active chlorine can vary between different brands or formulations.

Sodium hypochlorite is commonly used as a disinfectant and sanitizer due to its ability to kill a wide range of microorganisms, including bacteria, viruses, and fungi. It works by oxidizing the proteins and other essential components of these organisms, leading to their destruction.

In addition to its disinfecting properties, NaOCl is also a powerful bleaching agent. It is used in industries such as textile, paper, and pulp for the removal of stains and colorants. Sodium hypochlorite achieves bleaching by breaking down the chemical bonds in chromophores, which are responsible for the coloration of substances.

However, it is important to handle NaOCl with care as it is a corrosive substance and can cause irritation or burns to the skin, eyes, or respiratory system. It should be stored in a cool, dry place away from acids, flammable substances, and direct sunlight.

In summary, NaOCl or sodium hypochlorite is a chemical compound widely used as a disinfectant and bleaching agent. Its properties allow for effective killing of microorganisms and removal of stains and colors. However, caution should be exercised when handling and storing this chemical.
