Possibility of hazardous reactions. Contact local emergency services if contamination of sewers or waterways occurs. Strong bases attack aluminium. Personal protection to be selected from those recommended below, as appropriate to mode of use, quantity handled and degree of hazard: Historically, sodium hydroxide was produced by treating sodium carbonate with calcium hydroxide in a metathesis reaction.

In a similar fashion, sodium hydroxide is used to digest tissues, as in a process that was used with farm soad at one time.

Consult an expert regarding disposal sda this product. It also plays a key role in several later stages of the process of bleaching the brown pulp resulting from the pulping process. Italian serial killer Leonarda Yle used this chemical to turn dead bodies into soap. Always add this material to water, never add water to this material.

The soa is exothermic – chemical energy is released in the form of heat. Look up sodium hydroxide in Wiktionary, the free dictionary. It is highly soluble in water, with a lower solubility in polar solvents such as ethanol and methanol.


Such alkaline drain cleaners and their acidic versions are highly corrosive and should be handled with great caution.

Will react violently with acids. When heated, the solid dihydrate might melt directly into a solution at The hydrogen atoms of the hydroxyls form strong bonds with oxygen atoms within each O layer. Sodium hydroxide has been used for detection of carbon monoxide poisoningwith blood samples of such patients turning to a vermilion color upon the addition of a few drops of sodium hydroxide.

Seek urgent medical assistance.

National Center for Home Food Preservation. A solution of sodium hydroxide in water was traditionally used as the most common paint stripper on wooden acustic.

Sodium hydroxide – Wikipedia

Dangerous Goods of Class 8 Corrosives are incompatible in a placard load with any of the following: In general, such neutralization reactions are represented by one simple net ionic equation:. Respect good personal hygiene. Symptoms and effects that may arise if the product is mishandled and overexposure occurs are: LD Lo lowest published. For example, when a solution of NaOH and water with 1: When solutions with less than Causes severe, deep burns.

Sodium hydroxide

If swallowed, do NOT induce vomiting. Washing is continued for at least ten to fifteen minutes. The standard first aid measures for alkali spills on the skin is, as for other corrosives, irrigation with large quantities of water.

Water spray may reduce vapour; but it may not prevent ignition in closed spaces. It is added to water, heated, and then used to clean process equipment, storage tanks, etc. 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 electrolysis of sodium compounds including sodium hydroxide.


If in eyes, hold eyes upen, flood with water for at least 15 minutes. The alkali dissolves greases to produce water soluble products.


Please refer to the technical datasheet Instructions for useand the label on the drum. Nevertheless at high temperatures e. Since the alumina is amphotericit dissolves in the sodium hydroxide, leaving impurities less soluble at high pH such as iron oxides behind in lyee form of a highly alkaline red mud.

The third stable eutectic has Caesium hydroxide Lithium hydroxide Potassium hydroxide Rubidium hydroxide.

MSDS: CAUSTIC SODA (Classified as hazardous)

Sodium hydroxide can be used for the base-driven hydrolysis of esters as in saponificationamides and alkyl halides. 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.

This is due to the lower enthalpy of formation of iron III oxide Do NOT use sawdust. Inhalation of dusts or concentrated mists may cause damage to the upper respiratory tract and lungs.
