Sodium hydroxide is also widely used in pulping of wood for making paper or regenerated fibers. However, sodium hydroxide is not used as a primary standard because it is hygroscopic and absorbs carbon dioxide from air. If skin contact occurs, remove contaminated clothing and wash skin thoroughly.

Caustic Soda Lye

The aluminium takes the oxygen atom from sodium hydroxide, which in turn takes the oxygen atom from the water, and releases the two hydrogen atoms, The reaction thus produces hydrogen gas and sodium aluminate. InTrafigura used the process and then dumped the waste in Africa. Sodium hydroxide is a popular msdx base used in industry. Archived from the original PDF on Surfactants can be added to the sodium hydroxide solution in order to stabilize dissolved substances and thus prevent redeposition.

Sodium hydroxide causticc a highly caustic base and alkali that decomposes proteins at ordinary ambient temperatures cuastic may cause severe chemical burns. Seek urgent medical assistance. A hot water solution containing Sodium hydroxide is frequently used as an industrial cleaning agent where it is often called “caustic”. It describes the safety requirements for this product and should not be construed as guaranteeing specific properties.


However, at about 4.


Caesium hydroxide Lithium hydroxide Potassium hydroxide Rubidium hydroxide. The byproducts are hydrogen gas and heat, often resulting in a flame, making this a common demonstration of the reactivity of alkali metals in academic environments; however, it is not commercially viable, as the isolation of sodium metal is typically performed by reduction or lyw of sodium compounds including sodium hydroxide.

Hydrogen gas is generated when undiluted material contacts aluminium, zinc or tin. Oxidising agents, acids, acidic materials, ammonium compounds, nitro compounds, organic halides, active metals, wood, paper, glass.

Contact with aluminium, tin, zinc or galvanised iron may generate hydrogen, a flammable gas. Archived from the original PDF on September 14, Lithium hydroxide Potassium hydroxide Rubidium hydroxide.

Inhalation of dusts or concentrated mists may cause damage soca the upper respiratory tract and lungs.

As above, sodium hydroxide reacts with weak acids such as hydrogen sulfide and mercaptans to yield non-volatile sodium salts, which can be sod. Blanket the spill with foam or use water fog to disperse vapour clouds.

The information herein is to the best of our knowledge, correct and complete. When the concentration of airborne contaminants reach the exposure standards then the use of a half-face respirator with P1 filter is recommended.


Glass reacts slowly with aqueous sodium hydroxide solutions at ambient temperatures to form soluble silicates. In general, such neutralization reactions are represented by one simple jsds ionic equation:. By using this site, you agree to the Terms of Use and Privacy Policy. Along with sodium sulfidesodium hydroxide is a key component of the white liquor solution used to separate lignin from cellulose fibers in the kraft process.

Solid sodium hydroxide is most commonly sold as flakes, prillsand cast blocks. Refractive index n D. Like other corrosive acids and alkalisdrops of sodium hydroxide custic can readily decompose proteins and lipids in living tissues lyw amide hydrolysis and ester hydrolysiswhich consequently cause chemical burns and may induce permanent blindness upon contact with eyes. Such reactions are often used to ” scrub ” harmful acidic gases like Causticc 2 and H 2 S produced in the burning of coal and thus prevent their release into the atmosphere.
