Caustic Soda Specifications

Pure Sodium hydroxide (NaOH)

Sodium hydroxide, otherwise called Caustic Soda, is an inorganic compound with chemical formula NaOH. It is called caustic soda because it is highly corrosive in nature. It is available in many forms in the industry, and the most common forms are caustic soda flakes and caustic soda pearls. This product has several industrial applications but it is highly reactive, so it has to be used carefully lest, it can cause skin irritation.

Caustic Soda Flakes 98% Properties of Caustic Soda:
  • White solid
  • Highly caustic
  • Strong base
  • Soluble in water, ethanol and methanol
  • Readily absorbs water (hygroscopic) and carbon di oxide from the air
  • Strong electrolyte
  • Not volatile, but can rise easily in air as an aerosol
  • Dissolution of solid caustic soda in water in highly exothermic
Manufacturing Process for Caustic Soda:

Solid caustic soda is manufactured by evaporation of water from liquid caustic soda and then solidification into the required shape. Liquid caustic soda is manufactured by various processes such as the electrolysis of sodium hydroxide – technical grade, the Chloralkali process which is the electrolysis of sodium chloride, or the ammonia-soda process which is the reaction of brine and limestone.

Ammonia-soda process equation: 2 NaCl + CaCO3 → Na2CO3 + CaCl2
Chloralkali electrolyses process equations:
2NaCl + 2H2O → Cl2 + H2 + 2NaOH 2Na+ + 2Cl- + 2Hg → 2Na-Hg + Cl2 2Na-Hg + 2H2O →2NaOH + H2 + 2Hg
