Caustic Soda Lye Properties:
1. Chemical Formula: NaOH
2. Molecular Weight: 40.00 g/mol
3. Physical State: Caustic soda lye is usually found in the form of a colorless and odorless liquid.
4. Concentration: The concentration of caustic soda lye can vary, but common concentrations include 10%, 25%, 50%, and 73%. The concentration determines its strength and reactivity.
5. pH Level: Caustic soda lye is highly alkaline, with a pH level typically ranging from around 13 to 14.
6. Solubility: It is highly soluble in water, and the process of dissolving caustic soda in water generates a significant amount of heat.
7. Heat Generation: The dissolution of caustic soda in water is highly exothermic, meaning it releases a considerable amount of heat. This property should be considered when handling and diluting caustic soda.
8. Corrosive: Caustic soda lye is extremely corrosive to a wide range of materials, including metals, skin, and organic materials. It can cause severe burns and tissue damage upon contact.
9. Reaction with Acids: Caustic soda lye reacts vigorously with acids to form water and corresponding salts. This reaction is highly exothermic.

7. Water Treatment:
- Caustic soda is used for pH adjustment in water treatment processes, including drinking water and wastewater treatment.
- It can also be used for water softening, helping to remove hardness-causing minerals from water.
8. Food Processing:
- Caustic soda is used in food processing for cleaning and sanitizing equipment and facilities, especially in dairy and beverage industries.
9. Cleaning and Degreasing:
- It is used as a powerful degreaser and cleaner for various industrial equipment and surfaces.
Due to its highly corrosive and caustic nature, caustic soda lye should be handled with extreme care. Personal protective equipment (PPE) such as gloves, goggles, and protective clothing should be worn when working with it. Proper ventilation and handling procedures are essential to avoid accidents and injuries.
Caustic soda lye should be stored in a cool, dry, and well-ventilated area, away from incompatible materials (acids, metals, etc.). It should be stored in containers made of materials that are resistant to its corrosive effects, such as high-density polyethylene (HDPE) or glass.
