Caustic soda Flakes is an inorganic compound. It is a white solid and highly caustic metallic base and alkali of sodium which is available in pellets, flakes, granules, and as prepared solutions at different concentrations. Sodium hydroxide forms an approximately 95% (by mass) saturated solution with water. Sodium hydroxide is soluble in water, ethanol, and methanol. This alkali is deliquescent and readily absorbs moisture and carbon dioxide in air.
It is used in the refining of alumina containing ore like bauxite to produce aluminum oxide, a component of drilling mud and is used to increase viscosity, paper industries for making paper, manufacture of biodiesel, catalyst for the trans esterification of methanol and triglycerides, Used with water as paint stripper on wooden objects, to neutralize acids, a source of sodium ions for reactions that produce other sodium compounds, When Caustic Soda is reacted with cellulose, it produces rayon and cellophane, Pharmaceuticals, Water treatment.
