Caustic soda (sodium hydroxide) is a petrochemical that is solid, white, and soluble in water, with a melting point of 318 degrees Celsius. Among the characteristics of sodium hydroxide are its odorlessness, high corrosiveness, and its use as a raw material for industrial products.
Caustic soda is a chemical compound of sodium cation and hydroxide anion, which is alkaline and is considered a type of base and is used to neutralize acids. Today, caustic soda can be produced in the form of powder, pellets, flakes, solution, etc.
Sodium hydroxide is a white solid and is very caustic, causing severe burns if it comes in contact with the skin. Caustic soda (sodium hydroxide) can be used to unclog drains and make soap. It is also used to clean the drain pipe, remove accumulated fats and produce detergents.
