Description
What is SODIUM HYDROXIDE?
Sodium hydroxide, chemical formula NaOH, is a highly caustic and alkaline substance commonly known as caustic soda or lye. It is an inorganic compound composed of sodium (Na), hydrogen (H), and oxygen (O). NaOH is typically found in the form of white, odorless, and solid pellets, flakes, or granules.
Sodium hydroxide is a strong base and is highly reactive with water and various other substances. It is widely used in various industrial and chemical processes, including:
-
Chemical Manufacturing: NaOH is used in the production of various chemicals, including detergents, soaps, and paper.
-
Water Treatment: It is employed to adjust the pH levels of water in water treatment plants and in the treatment of wastewater.
-
Food Processing: Sodium hydroxide is used in food processing to peel fruits and vegetables (e.g., tomatoes, olives) and in the production of foods like pretzels and some canned goods.
-
Cleaning: It is a key ingredient in many household cleaning products such as drain cleaners and oven cleaners due to its ability to dissolve grease and oils.
-
Soap and Detergent Manufacturing: NaOH is crucial in the saponification process, where it reacts with fats and oils to produce soap.
-
Biodiesel Production: It is used in the production of biodiesel by converting triglycerides (fats and oils) into methyl esters.
-
Petroleum Refining: NaOH is used in the refining of petroleum products, such as removing impurities from crude oil.
-
Chemical Analysis: It is often used in laboratories to neutralize acids and for various chemical analysis procedures.
Sodium hydroxide should be handled with care as it is highly corrosive and can cause severe burns if it comes into contact with the skin. When using NaOH, appropriate safety precautions, such as wearing protective gear and working in a well-ventilated area, should be followed.
