Sodium hydroxide

It melts congruously at 7. For example, when a solution of NaOH and water with 1: It is used in the Bayer process of aluminium production.

Aluminium hydroxide is prepared at the treatment plant from aluminium sulfate by reacting it with sodium hydroxide or bicarbonate. Engineering control methods to reduce hazards are preferred.

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. msxs

Sodium hydroxide is frequently used as an industrial cleaning agent where it is often called “caustic”. Caustid materials that are compatible with sodium hydroxide and often utilized for NaOH storage include: Store in original packages as approved by manufacturer.

Hygroscopic, will absorb moisture from the air. Sodium hydroxide is used in many scenarios where it is desirable to increase the alkalinity of a mixture, or to neutralize acids.

Sodium hydroxide relaxers are still osda, but they are used mostly by professionals. Do not use aluminium, tin, zinc or galvanised iron as materials of construction. Archived from the original PDF on September 14, Thus, protective equipmentlike rubber glovessafety clothing and eye protectionshould always be used when handling this chemical or its solutions. Lithium battery cellsif ingested, cause serious injuries, even if not crushed. Contact with ammonium compounds will generate ammonia, a poisonous gas.


Physical and chemical properties. Longmans, Green, and Co. Blanket the spill with foam or use water fog to disperse vapour caudtic. These reactions are sped by the heat generated when sodium hydroxide and the other chemical components of the cleaner dissolve in water. The resulting solution is usually colorless and odorless.

Caustic Soda Lye (NaOH)

Inhalation of dusts or concentrated mists may cause damage to the upper respiratory tract and lungs. Contact local emergency services if contamination of sewers or waterways occurs. Check all fittings, valves, reticulation piping and any ancillary equipment for leaks. The information herein is to the best of our knowledge, correct and complete. Caesium hydroxide Lithium hydroxide Potassium hydroxide Rubidium hydroxide. Sodium hydroxide also reacts with acidic oxidessuch as sulfur dioxide.

Take up with sand, dirt or vermiculite. It can dissolve greaseoilsfats and protein -based deposits. Hydrogen gas is generated when undiluted material contacts aluminium, zinc or tin. Rinse cautiously with water for several minutes. Flasks and glass-lined chemical reactors are damaged by long exposure to hot sodium hydroxide, which also frosts the glass.

Italian serial killer Leonarda Cianciulli used this chemical to turn dead bodies into soap. Sodium hydroxide is traditionally used in soap making cold process soap, saponification.


Conversely, by applying heat energy into a dilute sodium hydroxide solution the water will evaporate so that the solution becomes more concentrated and thus stores the supplied heat as latent caaustic energy. Retrieved from ” https: All equipment must be earthed.

May react violently with organic halides.

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

A few transition metalshowever, may react vigorously with sodium hydroxide. As with other alkaline solutions, it feels slippery with skin contact due to the process of saponification that occurs between NaOH and natural skin oils. Causes severe, deep burns. 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.

When in the French chemist and surgeon Nicolas Leblanc — patented a process for mass-producing sodium caustinatural “soda ash” impure sodium carbonate that was obtained from the ashes of plants that are rich in sodium [47]: Reactions with mineral acids generate heat. Sodium hydroxide is also used in the manufacture of sodium salts and detergents, pH regulation, and organic synthesis.

Qily is the ashes of certain plants, e.

H Causes severe skin burns and eye damage.
