Sodiumhydroxide (Na OH), also known as lye and caustic soda, is a caustic metallic base. It is used
in many industries, mostly as a strong chemical base in the manufacture of pulp and paper, textiles, drinking water, soaps and detergents and as a drain cleaner. Worldwide production in 1998 was around 45 million tonnes. Sodiumhydroxide is a common base in chemical laboratories.
Pure sodiumhydroxide is a white solid; available in pellets, flakes, granules and as a 50%saturated
solution. It is hygroscopic and readily absorbs water fromthe air, so it should be stored in an airtight container. It is very soluble in water with liberation of heat. It also dissolves in ethanol and methanol, though it exhibits lower solubility in these solvents than does potassium hydroxide. Molten sodium hydroxide is also a strong base, but the high temperature required limits applications. It is insoluble in ether and other non-polar solvents.Asodium hydroxide solution will leave a yellow stain on fabric and paper.
