Potassium Hydroxide

The Chemical Compound potassium hydroxide ( K OH ), sometimes known as '''caustic Potash ''', '''potassa''', '''potash Lye ''', and '''potassium hydrate''', is a Metallic Base . It is very Alkaline and is a "strong base", along with Sodium Hydroxide , Lithium Hydroxide , Calcium Hydroxide , Barium Hydroxide and Strontium Hydroxide .

USES

Agriculture

Correction of the PH of acidic soils

As a Fungicide

As an Herbicide

Manufacturing and commercial chemical processes

KOH is a major industrial chemical because it is 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 (raises pH by neutralizing acids)

Making Polyethylene resins

Textile processing

As a Catalyst in reactions like the production of Biodiesel .

Manufacture of many cleaning products, such as:

--- Washing powders

--- Cleansers (for tubs, tile, etc)

--- Some Denture cleaners

--- Non- Phosphate Detergent s

--- Drain or pipe cleaners (clog dissolvers)

Manufacture of Alkaline Batteries , which use an aqueous solution of KOH as an electrolyte. Thus, potassium hydroxide helps to power flashlights, smoke detectors, and other battery-powered household items.

As an Anisotropic etchant of Silicon , exposing Octahedral planes. This technique can create pyramids and regularly-shaped etch pits for uses such as Microelectromechanical Systems .

Medicine (human and veterinary)

KOH Test (to diagnose Fungal Infections )

Whiff Test (to diagnose Bacterial Vaginosis )

Wart and Cuticle solvent

('' Veterinary Medicine '') disbudding calves horns; dissolving scales and hair

Food preparation

Food uses of lye include:

Washing or chemical peeling of Fruits and Vegetables

Chocolate and Cocoa processing

Caramel Color production

Poultry scalding

Soft Drink processing

Thickening Ice Cream

Soaking of Olives to soften them and neutralize natural acids

Glazing of Pretzel s and German Lye Roll s before baking to make them crisp.

Soaking of Cod to make the Scandinavia n delicacy known as Lutefisk (from ''lutfisk'', "lye fish"). Cod is soaked in lye to a jelly-like consistency, then served with Bacon fat, Potatoes , brown cheese ( Brunost ) sauce and mushy Pea s.

Making of Hominy , which is dried Maize (corn) kernels reconstituted by soaking in lye.
