Sodium hydroxide is caustic and is one of several alkaline compounds referred to as "lye." It is generally used commercially as either the solid or as a 50% aqueous solution and should be stored in a cool, dry, well ventilated location separate from organic and oxidizing materials, acids, and metal powders. Synonyms include caustic soda, lye ...
