The Caustic Potashis 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 (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 highthermal stability. Thegaseousspecies isdimeric. Because of its high stability and relatively lowmelting 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 reactingsodium hydroxidewith impurepotassium. It is usually sold as translucent pellets, which will become tacky in air because KOH ishygroscopic. Consequently, KOH typically contains varying amounts of water (as well as carbonates - see below). Itsdissolutionin water is stronglyexothermic. Concentrated aqueous solutions are sometimes called potassiumlyes. Even at high temperatures, solid KOH does not dehydrate readily.
