Incompatible materials, exposure to moisture or air.

Adjacent O layers are held together by hydrogen bonds between water molecules. It describes the safety requirements for this product and should not be construed as guaranteeing specific properties. May react violently with organic halides.

Sodium hydroxide – Wikipedia

If in eyes, hold eyes upen, flood with water for at least 15 minutes. Thus, protective equipmentlike rubber glovessafety clothing and eye protectionshould always be used when handling this chemical or its solutions.

This happens because oils on the skin such as sebum are converted to soap. Multi purpose heavy duty alkaline cleaner. Journal of Physical Chemistryvolume 66, issue 10, pages — Engineering control methods to reduce hazards are preferred. Remove all ignition sources and safely stop flow of spill.

Other amphoteric metals are zinc and lead which dissolve in concentrated sodium hydroxide solutions to give sodium zincate and sodium plumbate respectively. A sodium hydroxide soak solution is used as a powerful degreaser on stainless steel and glass bakeware.

  ISO 19438 PDF

If a dilute solution is spilled on the skin, burns may result if the area is not washed thoroughly and for several minutes with running water. Cxustic form shock-sensitive products with organic nitro compounds.

The standard first aid measures for alkali spills on the skin is, as for other corrosives, irrigation with large quantities of water.

Physical and chemical properties. Sodium hydroxide is also widely used in pulping of wood for making paper or regenerated fibers. Vomiting has not been induced because of risk of aspiration into the lungs.

Caustic Soda Lye (NaOH)

Prolonged contact may cause severe eye irritation and some form of permanent eye damage may occur. May cause redness, pain, blurred vision. The hydrogen atoms of the hydroxyls form strong bonds with oxygen atoms within each O layer. Owing to the difficulty in obtaining food grade sodium hydroxide in small quantities for home use, sodium carbonate is often used in place of sodium hydroxide. Since the alumina is amphotericit dissolves in the sodium hydroxide, leaving impurities less soluble at high pH such as iron oxides behind in the form of a highly alkaline red mud.

Such alkaline drain cleaners and their acidic versions are highly corrosive and should be handled with great caution. Getting rid of dirt — and murder victims”. For the manufacture of biodieselsodium hydroxide is used as a catalyst for the transesterification of methanol and triglycerides.

May react with sugars to generate carbon monoxide, a toxic, odourless gas. From Wikipedia, the free encyclopedia. Increased pH makes the water less corrosive to plumbing and reduces the amount of lead, copper and other toxic metals that can dissolve into drinking water.


Sodium hydroxide is often stored in bottles–as in laboratories, small-scale use–within intermediate bulk containers –medium volume containers for cargo handling and transport–or within large stationary osda tanks msdx volumes up togallons–as in manufacturing or waste water plants with extensive NaOH use.

Inhalation of dusts or concentrated mists may cause damage to the upper respiratory tract and lungs. Remove contact lenses, if present and easy to do. Operators are recommended to wear full protective clothing, glasses, gloves, apron etc. In this reaction, sodium hydroxide acts as an agent to make the solution alkaline, which aluminium can dissolve in. Products that contain alkali hydroxides must be kept away from non-ferrous metals, as extremely flammable hydrogen gas will be generated and if the appropriate flammability limits are reached and a source of ignition is present, a violent explosion will occur.

Journal of Physical Chemistryvolume 73, issue 1, pages — Water spray may reduce vapour; but it may not prevent ignition in closed spaces. Oxidising agents, acids, acidic materials, ammonium compounds, nitro compounds, organic halides, active metals, wood, paper, glass.
