Caustic soda, also known as sodium hydroxide (NaOH), is corrosive and a highly active chemical substance. This is a snow-white substance in the form of flakes or granules. Very hygroscopic, well soluble in water. When dissolved in water, a large amount of heat is released.
Here are some of its main properties:
· Alkaline reactivity: Caustic soda has a high reactivity with acids, which allows it to be used for degreasing and cleaning equipment.
· High alkalinity: Caustic soda is a very alkaline solution with a pH of about 14, which allows it to be used to neutralize acids in water and other liquids.
· Hydrophilicity: Caustic soda is a hydrophilic compound, that is, it is able to bond with water and attract moisture.
Caustic soda is used in many industries and for household purposes:
· Papermaking: Caustic soda is used in papermaking as a solvent and to remove dirt and color from pulp.
· Manufacture of soaps and detergents: Caustic soda is added to fats to turn them into soap.

· Fertilizer production: Caustic soda is used as an ingredient in the production of fertilizers such as potassium sulfate.
· Polymer production: Caustic soda is used to produce polymers such as polyacrylonitrile and polyester.
· Water purification: Caustic soda is used to purify water from bacteria and other impurities.
· Glass production: Caustic soda is used in glass production as a solvent for mixing the glass mixture.
· Food industry: Caustic soda is used to treat certain foods such as
grains that need to be defatted.
· Caustic soda is a highly alkaline substance that reacts with acids commonly used to remove oxidation from metals and clean pipelines.
· Caustic soda can be used in everyday life to remove stains and clean surfaces and as a means to solve problems with clogging of sewer pipes.
