【Use of Potassium hydroxide】:
   In agriculture , potassium hydroxide is used to correct the pH of acidic soils. It can also be used as a fungicide or even an herbicide .
   It is a major industrial chemical used as a base in a wide variety of chemical processes. Some uses of KOH include acrylate ester copolymer coating, defoaming agents used in the manufacture of paper , saponifying oils for liquid soap, formulation aid for food, pH control agent, polyethylene resins, textile processing and as a catalyst in reactions like the production of biodiesel.
   Other uses include in veterinary medicine in disbudding calves horns and to dissolve scales and hair; in human medicine , to diagnose fungal infections and as a wart and cuticle solvent; manufacture of cleansers. This type of compound is also used in washing powders, some denture cleaners, non- phosphate detergents , and drain or pipe cleaners.
   A very significant use of KOH in terms of significance to the layperson is that alkaline batteries use an aqueous solution of KOH as an electrolyte. Thus, potassium hydroxide helps to power flashlights, smoke detectors, and other battery-powered household items.It is also an anisotropic etchant of silicon , exposing octahedral planes. This technique can create pyramids and regularly-shaped etch pits for uses such as microelectromechanical systems.
