Potassium hydroxide
Potassium hydroxide
Potassium hydroxide (caustic potash), KOH - an inorganic chemical compound from the group of hydroxides, one of the strongest bases.
Under standard conditions, potassium hydroxide is a white solid. As a chemical reagent, it is usually produced in the form of brittle, crystalline, soft flakes or granules with a water content of approx. 15%. It has strong hygroscopic properties, larger than sodium hydroxide. It dissolves very well in water; the dissolution process is strongly exothermic. The solution, called potassium lye, is strongly alkaline. Potassium hydroxide and its aqueous solution absorb carbon dioxide from the air to form potassium carbonate, therefore it should be stored in sealed containers. It is highly corrosive, it can cause serious burns. If swallowed, causes burns in the esophagus and stomach, it may cause perforation.
