Sodium Hydroxide (Caustic Soda)

Sodium Hydroxide, also known as lye, caustic soda and, incorrectly, according to IUPAC nomenclature, sodium hydrate, is a caustic metallic base. Sodium hydroxide forms a strong alkaline solution when dissolved in a solvent such as water. Pure sodium hydroxide is a white solid; commercially available in pellets, flakes, granules and as a 50% saturated solution. It is deliquescent and readily absorbs carbon dioxide from the 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 potassium hydroxide. It is insoluble in ether and other non-polar solvents.

Install a facility that can discharge large quantities of water to flush away any accidentally leaked or spilt caustic soda. Although caustic soda must be handled with care so as not to leak, in case of
leakage follow the procedures in Section VI Action to be Taken in Case of Leakage When solid caustic soda is being taken out of a drum, cut the seam of the drum. Since solid caustic soda taken from a drum quickly absorbs moisture from the atmosphere and becomes slippery, take great care not to slip on it In the case of liquid caustic soda, carefully remove the cap of the drum while standing it in the upright position, and connect a nipple pipe. Lay the drum down with its air purging valve facing upward and loosen the valve to introduce air into the drum, then open the valve to take out the liquid.
