Key Properties
Sodium hydroxide pellets (extra pure, caustic soda pellets) is a convenient pellet form of this widely used strong base. It is a highly soluble ionic compound that dissociates completely in water to yield hydroxide ions, making it an essential reagent in various chemical processes. With a purity of 97%, these pellets are suitable for demanding applications in laboratories and industrial settings. Sodium hydroxide is known for its strong alkaline properties and is commonly used in the production of soaps, detergents, and various chemical syntheses.
Also known as Caustic soda, Lye.
