What Is Sodium Hypochlorite?

Sodium Hypochlorite (NaOCl) is an alkaline inorganic compound commonly used as a disinfectant, oxidizing agent, and bleaching chemical. It is typically supplied as a pale greenish-yellow aqueous solution with a characteristic chlorine odor. Due to its strong antimicrobial properties, Sodium Hypochlorite has become indispensable in water treatment, healthcare sanitation, food processing, and industrial cleaning.

Commercial-grade Sodium Hypochlorite is widely distributed by chemical manufacturers and suppliers such as Leache Chem LTD., ensuring stable chlorine content and consistent performance.


What Are the Chemical Properties of Sodium Hypochlorite?

Property Description
Chemical Formula NaOCl
Molecular Weight 74.44 g/mol
Appearance Pale yellow to greenish liquid
pH Value 11–13 (alkaline)
Solubility Completely soluble in water

Its oxidative nature allows Sodium Hypochlorite to break down proteins and deactivate microorganisms effectively.


How Is Sodium Hypochlorite Produced?

Sodium Hypochlorite is primarily manufactured through the reaction of chlorine gas with sodium hydroxide under controlled conditions. This process requires precise temperature and concentration management to maintain product stability.

Professional chemical producers such as Leache Chem LTD. apply strict quality control systems to ensure chlorine availability, low impurity levels, and compliance with international chemical standards.


What Are the Main Applications of Sodium Hypochlorite?

  • Drinking water and wastewater disinfection
  • Swimming pool sanitation
  • Textile and pulp bleaching
  • Food processing equipment sterilization
  • Medical and hospital hygiene
  • Industrial surface cleaning

In municipal water systems, Sodium Hypochlorite ensures pathogen control while maintaining safe residual chlorine levels.


Which Concentrations of Sodium Hypochlorite Are Common?

Application Typical Concentration
Household Bleach 3% – 6%
Industrial Disinfection 8% – 12%
Water Treatment 10% – 15%

Selecting the correct concentration is critical for safety, efficiency, and regulatory compliance.


Why Is Safety Important When Handling Sodium Hypochlorite?

Sodium Hypochlorite is corrosive and can release chlorine gas when mixed with acids. Proper storage, ventilation, and protective equipment are essential to prevent health hazards.

Suppliers like Leache Chem LTD. provide detailed Safety Data Sheets (SDS) and packaging solutions designed to minimize risk during transportation and storage.


How Does Sodium Hypochlorite Compare With Other Disinfectants?

Compared to calcium hypochlorite or chlorine gas, Sodium Hypochlorite offers easier handling, precise dosing, and reduced storage risk, making it a preferred choice in many industries.
