Detailed Product Description:

A white crystalline powder.  Strong base.  Soluble in water, alcohol

and glycerol.  Used as an absorbent for carbon dioxide and as an

electrolyte in alkaline batteries and in some fuel cells.


Potassium Hydroxide (KOH), sometimes known as caustic potash,

potassa, potash lye, and potassium hydrate, is a metallic base.  It is

extremely alkaline and is considered a "strong base", along with

sodium hydroxide, lithium hydroxide, calcium hydroxide, barium

hydroxide and strontium hydroxide. 


Pure potassium hydroxide is a colorless, highly hygroscopic, solid

Crystalline compound, having a density of about 2.04 g/cm3, readily

soluble in water and lower alcohols (methanol, ethanol, propanols),

as well as other polar solvents.


The dissolution of potassium hydroxide in water is strongly exothermic,

releasing significant heat energy leading to temperature rise sufficient

enough to reach the boiling point.


Potassium hydroxide forms solid hydrates, namely the monohydrate

KOH·H2O, the dihydrate KOH·2H2O, and the tetrahydrate KOH·4H2O.

This characteristic allows for its use as a highly intensive desiccant

agent, e.g. for drying liquid amines or their solutions in indifferent,

nonpolar solvents (such as hydrocarbons).


It is a highly basic compound, forming strongly alkali solutions in

water and other polar solvents, capable of deprotonating many acids,

even weak ones, and decomposing some inorganic as well as organic

materials (e.g. dissolution and hydrolysis of broken glass or fats in

concentrated KOH solutions).


It is an important industrial chemical, used to manufacture many

industrial, as well as commercial goods and products.  It's also an

important laboratory chemical and reagent, used to prepare potassium

salts, to neutralize acids, further as basic standard in analytics and

many more applications.



This is ACS Reagent Grade material with a minimum purity of 99.8%



As a very strong base/alkali, potassium hydroxide is strongly corrosive,

both towards inorganic as well as organic materials, including living

tissues.  Care must be exercised when handling the substance and its

solutions.  Its corrosivity is sometimes exploited in cleaning and disinfection

of resistant surfaces and materials.  Toxic by ingestion and inhalation. 

Corrosive to tissue.  Download, read and understand MSDS before using

this substance.
