Caustic soda, also known as sodium hydroxide (NaOH), is a highly caustic and alkaline compound that is widely used in various industries. It is produced by the electrolysis of sodium chloride (salt) and is available in solid form (flakes or pellets) or liquid form. Caustic soda is highly reactive and can cause severe burns upon contact with skin or eyes.
Industrial Uses of Caustic Soda:
• Chemical Manufacturing: Caustic soda is used in the production of chemicals such as soap, detergents, and synthetic fabrics. It is a key ingredient in the production of chlorine and sodium carbonate.
• Pulp and Paper Industry: It is used to dissolve lignin in wood fibers during the paper manufacturing process.
• Water Treatment: Caustic soda is used to neutralize acids and adjust the pH of water in treatment plants.
• Food Processing: In food production, caustic soda is used to peel fruits and vegetables, and it is also involved in some food preservation processes.
Safety and Handling:
Due to its highly corrosive nature, it is crucial to handle caustic soda with extreme care, wearing appropriate safety gear and following established safety protocols.
