Caustic soda or Sodium hydroxide is a white solid substance with the chemical formula NaOH. It is obtained through the process of electrolysis of sodium chloride soluble in the electrolytic containers. Caustic soda is an essential ingredient in many industrial and commercial applications. It is a strong, colourless alkali. Since this product is highly corrosive in nature, it is called caustic soda.
Caustic soda is widely used in different industries such as pulp and paper, detergents, packaging, agriculture, water treatment, food, textiles, etc.
Caustic Soda is mostly sold as an aqueous solution, but depending on the applications, it is commercially available in solid granules, flakes or concentrated solids.
Characterization of Caustic soda
Caustic Soda is a white solid substance with the chemical formula NaOH. It is highly soluble in water, with a lower solubility in polar solvents like methanol and ethanol. This substance is highly hygroscopic and absorbs the moisture, carbon dioxide, or sulfur dioxide in the air. Caustic soda specifications include:
- Its molar mass is 997 g. mol-1.
- Its melting point is 323 ℃.
- Its boiling point is 1388 ℃.
- Its density is 13 g/cm³.

Applications of Caustic soda
Caustic soda (NaOH) is one of the most important chemical raw materials. NaOH is used in organic chemistry, in the production of aluminium, in the paper industry, in the food processing industry, in the manufacture of detergents, etc. Different uses of Caustic soda in various industries include:
- Pulp and paper
- Soaps and detergents
- Water treatment
- Oil and gas
- Food industry
- Chemical industry
- Leather and textile industries
- Pharmaceuticals like blood thinners
Caustic soda production
Caustic soda is produced by passing a powerful electric current through a brine solution (salt dissolved in water). The resultant chemical reaction produces chlorine and caustic soda, or chlorine and caustic potash.
Caustic soda is produced in liquid and solid forms. Liquid caustic soda is a strong base used as a chemical reagent, a pH regulator, catalyst and a cleaning agent. Solid caustic soda has similar properties but is manufactured by evaporation of water from liquid caustic soda, followed by solidification into micro pearls.
Caustic soda storage
Caustic soda should be stored in a cool, dry, and well-ventilated area. Other storage conditions include:
- Caustic soda should be kept away from incompatible materials such as strong acids, metals, explosives, organic peroxides and so on.
- It should be kept away from volatile materials.
- Caustic soda should be stored at room temperature in a dry and well-ventilated area.
Caustic soda health hazards
Caustic soda which is highly alkaline, can have corrosive properties while having moisture such as water vapor.
when working with Caustic soda or its solutions, you should always use protective equipment such as rubber gloves, safety clothing and goggles.
In the case of contact of caustic soda solution with the skin, first aid measures include washing the area with a large volume of water. Washing should continue for at least 10-15 minutes.
FAQ
What is Caustic soda?
Caustic Soda is a white solid substance with the chemical formula NaOH. It is highly soluble in water, with a lower solubility in polar solvents like methanol and ethanol. Caustic Soda is used in the manufacture of paper, textiles, detergents, soaps, etc.
What is Caustic Soda used for?
Caustic soda is widely used in pulp and paper, detergents, packaging, agriculture, environmental protection, water treatment, textiles and construction.
Is Caustic soda the same as NaOH?
Caustic soda is one of the common names for sodium hydroxide (NaOH), which is also known as lye. In pure form, caustic soda is a waxy, white solid. It readily absorbs water and forms aqueous solutions.
What are the storage conditions of liquid Caustic soda?
Caustic Soda solution is stable. However, if this chemical comes into contact with air, the product’s quality will degrade over time, as Caustic Soda absorbs carbon dioxide from the surrounding air and forms solid sodium carbonate (Na2CO3) particles. Therefore, contact between Caustic Soda Liquid and air should be kept to a minimum.
