This inorganic chemical compound is one of the strongest bases. In solid form, it is a white substance with a crystalline structure (flakes or granules)). It has hygroscopic properties (caking). It perfectly dissolves in water, thereby forming a corrosive soda lye, which is accompanied by the release of significant amounts of heat – a strong exothermic reaction. Its use is like sodium hydroxide 50%. Caustic soda is packed in a 25 kg bag, which facilitates its storage and storage.
