Sodium hydroxide is a common base in chemical laboratories.
Pure sodium hydroxide is a white solid; available in pellets, flakes, granules and as a 50% saturated solution. It is and readily absorbs from the air, so it should be stored in an container. It is very soluble in water with liberation of heat. It also dissolves in and , though it exhibits lower solubility in these solvents than does . Molten sodium hydroxide is also a strong base, but the high temperature required limits applications. It is insoluble in and other non-polar solvents. A sodium hydroxide will leave a yellow stain on fabric and paper.
