Updated on February 03, 2020. Caustic soda is one of the common names for sodium hydroxide (NaOH), which is also known as lye. Its common name derives from its chemical identity as a sodium hydrate and because it is caustic or corrosive. In pure form, caustic soda is a waxy, white solid. It readily absorbs water and forms aqueous solutions.Web

Chlorine occurs naturally but not in its elemental (gas) form (as Cl 2 ). Caustic soda (usually as NaOH) is produced as a liquid. These are produced by passing an electrical current through brine (common salt dissolved in water). This is called electrolysis, a process which has been known for over 120 years.Web
