The Caustic PotashÂ is also known as potassium hydroxide or caustic potash. They are extremely versatile and are basically used as cleaning agent. Apart from this they are highly basic, forming strongly alkaline solutions in water and other polar solvents. The Caustic Potash (Â are capable of deprotonating many acids. They are also used as assay acids. Further they are provided in a sealed container to keep them sealed and safe. Further they are free from impurities and moisture & are available at reasonable time.
Like NaOH, KOH exhibits highÂ thermal stability. TheÂ gaseousÂ species isÂ dimeric. Because of its high stability and relatively lowÂ melting point, it is often melt-cast as pellets or rods, forms that have low surface area and convenient handling properties.
Potassium hydroxide can be found in pure form by reactingÂ sodium hydroxideÂ with impureÂ potassium. It is usually sold as translucent pellets, which will become tacky in air because KOH isÂ hygroscopic. Consequently, KOH typically contains varying amounts of water (as well as carbonates - see below). ItsÂ dissolutionÂ in water is stronglyÂ exothermic. Concentrated aqueous solutions are sometimes called potassiumÂ lyes. Even at high temperatures, solid KOH does not dehydrate readily.
