Caustic Soda Sodium

Product: Caustic Soda Sodium

 

Other names: Caustic soda, Lye, Sodium hydroxide

 

Molecular Formula: Na OH

 

CAS number: 1310-73-2

 

Appearance: white solid, hygroscopic

 

Solubility in water: 111 g/100 ml (20 °C)

 

Safety:

Solid sodium hydroxide or solutions of sodium hydroxide will cause chemical burns, permanent

injury or scarring, and blindness if it contacts unprotected human or animal tissue. Protective

equipment such as rubber gloves, safety clothing and eye protection should always be used when

handling the material or its solutions. Dissolution of sodium hydroxide is highly exothermic, and the resulting heat may cause heat burns or ignite flammables.

 

Brief introduction:

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.
