What is Potassium Hydroxide?
Potassium hydroxide (KOH) is an inorganic caustic compound. It is extremely alkaline and is known for its powerful exothermic reaction when dissolved in water. The substance is highly hygroscopic with a boiling point of 1327 oC. It is also soluble in alcohols, ammonia and glycerol. It is sometimes more commonly known as caustic potash.Aside from the obvious risk when dissolved in water, potassium hydroxide is extremely corrosive at concentrations of 2%. It should, therefore, only be handled by trained and qualified persons. As with all foreign chemicals, care and caution should be exercised when working with these substances.
What is Caustic Potash Used For?
KOH has many similar uses to sodium hydroxide (NaOH) and as such is often substituted for its daily applications. Some examples of these applications are:
Used in soft soaps through esterification reaction in the presence of triglycerides
Used as an electrolyte in alkaline batteries – KOH is a better electrical conductor that NaOH
Due to the corrosive nature of the product, it is commonly used in cleaning products
Due to the high solubility of the product, it is commonly added to plant fertilisers
Used in the manufacture of biodiesel
Used to identify species of fungi in biological applications
