Will react vigorously or violently with acids, generating much heat, and giving off carbon dioxide, a simple asphyxiant.

It is also a common ingredient in oven cleaners. Reaction with non-ferrous metals generates hydrogen gas which may cause explosion under appropriate conditions. In other projects Wikimedia Commons. Common materials that are compatible with sodium hydroxide and often utilized for NaOH storage include: A sodium hydroxide soak solution is used as a powerful degreaser on stainless steel and glass bakeware. A second stable eutectic composition is Do not use aluminium, tin, zinc or galvanised iron as materials of construction.

Prevent spills from entering drains and waterways. Tell them exact location, nature, hazards, quantities, type of vehicle and any other information that would be helpful.

Caustic Soda Lye

Journal of Physical Chemistryvolume 78, issue 17, pages — Contact local emergency services if contamination of sewers or waterways occurs. The resulting solution is usually colorless and odorless. Sodium hydroxide is frequently used as an industrial cleaning agent where it is often called “caustic”.


If water is added to solid or concentrated sodium hydroxide NaOHheat is released. Sodium hydroxide also reacts with acidic oxidessuch as sulfur dioxide.

Recycle packaging by replacing cap and returning clean containers to recycler or designated collection point. May cause perforation of the stomach and intestines, and the sites of subsequent scarring have been associated with the later development of mds cancer.


These reactions are sped by the heat generated when sodium hydroxide and the other chemical components of the cleaner dissolve in water. May react with sugars to generate carbon monoxide, a toxic, odourless gas. The alkali dissolves greases to produce water soluble products. Adjacent O layers are held together by hydrogen bonds between water molecules. Touching sodium hydroxide solution with the bare hands, while not recommended, produces a slippery feeling. 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.

The sodium hydroxide-based detergents include surfactants, rust inhibitors and defoamers.


Sodium hydroxide used in this manner replaced many solvent-based systems in the early s [ citation needed ] when trichloroethane was outlawed by the Montreal Protocol. Precautions for Safe Handling.

ICCA Sodium hydroxide (Na(OH)) Information on Safety, Hazards, Effects, Risks & Toxicity

When solutions with less than In general, such neutralization reactions are represented by one simple net ionic equation:. Dangerous Goods of Class 8 Corrosives are incompatible in a placard load with any of the following: 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.

Retrieved January 15, Will attack wood and paper products, and glass on prolonged contact.

Chemical engineering Cleaning products Deliquescent substances Desiccants Household chemicals Hydroxides Inorganic compounds Photographic chemicals Sodium compounds Bases chemistry E-number additives. If swallowed, may cause holes in stomach and intestines. May cause swelling of the larynx and subsequent suffocation. Italian serial killer Leonarda Cianciulli used this chemical to turn dead bodies into soap. Remove victim to fresh air.
