Sodium Hydroxide

Sodium hydroxide, also known as caustic soda or lye, is a highly caustic and corrosive substance. It is a white, solid compound in its pure form but is commonly sold as a concentrated solution. Sodium hydroxide is highly soluble in water and has a wide range of applications in various industries. It is primarily used in water treatment as a pH regulator, where it can raise the pH of acidic water. Sodium hydroxide is also employed in the manufacturing of soaps, detergents, paper, textiles, and various chemical processes. It is known for its strong alkaline properties and should be handled with caution due to its corrosive nature. Its specifications are:

  • Chemical Formula: NaOH
  • Physical State: White, solid flakes or pellets (pure form)
  • Solubility: Highly soluble in water
  • pH: Highly alkaline substance with a pH above 13 in solution
  • Density: Approximately 2.13 g/cm³ (solid form)
  • Melting Point: 318 °C (604 °F)
  • Boiling Point: 1,388 °C (2,530 °F)
  • Odor: Odorless
  • Stability: Stable under normal conditions

Sodium Hydroxide Uses in Water Treatment

Sodium hydroxide (NaOH) serves several important purposes in water treatment processes. It is commonly used as a pH adjuster, helping to raise the pH of acidic water to achieve desired levels. Sodium hydroxide is particularly useful in neutralizing the acidity of water and balancing its chemistry. Additionally, it aids in the coagulation and flocculation processes, promoting the clumping of fine particles and impurities for easier removal during sedimentation or filtration. Sodium hydroxide also plays a role in water disinfection, as it helps to enhance the effectiveness of chlorine-based disinfectants by adjusting the pH to an optimal range. However, caution should be exercised when handling sodium hydroxide, as it is a highly caustic substance that can cause severe burns and damage to organic tissues.
