Sodium Hypochlorite Solution NaClO Be Used To Disinfect Drinking Water 

Sodium hypochlorite is unstable and decomposes easily when exposed to light or heat. Therefore, it mostly exists in the form of solutions in daily life and industrial production. Although solids can be theoretically produced, they are generally more common in laboratories. At present, the production methods of sodium hypochlorite include electrolysis and caustic soda chlorination, etc.

Preparation of sodium hypochlorite solution

Chlorine gas dissolves in cold and dilute sodium hydroxide solution to produce sodium hypochlorite, sodium chloride and water.

Cl2 + 2NaOH → NaClO + NaCl + H2O

Note that when chlorine gas dissolves in hot and concentrated sodium hydroxide solution, it does not produce sodium hypochlorite, but generates sodium chloride, sodium chlorate and water.

3Cl2 + 6NaOH → 5NaCl + NaClO3 +3H2O

Sodium hypochlorite is a strong oxidant with a wide range of applications. The following are some common application fields:

Medical and health care: It is often used for disinfection in hospital environments, medical devices, wards, etc., and can effectively kill various bacteria, such as Escherichia coli, Staphylococcus aureus, Candida albicans, etc., preventing cross-infection.

Food processing: It can be used for disinfection of food processing equipment and containers, as well as environmental disinfection in food production workshops, ensuring the hygiene and safety of the food production process. At the same time, it can also be used for disinfecting drinking water, killing bacteria and viruses in water to ensure the safety of drinking water.

Daily life: In the family, it can be used for disinfecting tableware, clothes, etc. For instance, soaking tableware in diluted sodium hypochlorite solution for a period of time can effectively remove bacteria and viruses. In addition, it can also be used for cleaning and disinfection in places such as bathrooms and kitchens, removing odors and killing bacteria.

Bleaching
Textile industry: It is used for bleaching natural fibers such as cotton, linen, silk and wool, as well as chemical fibers, to make fabrics achieve a white and bright effect. For instance, sodium hypochlorite is one of the commonly used bleaching agents in the production process of textiles such as towels and bed sheets.

Papermaking industry: It can bleach pulp, improving the whiteness and quality of paper. By removing pigments and impurities from the pulp, the paper becomes whiter and smoother, making it suitable for the production of various printing, writing and packaging papers.
