potassium hydroxide

n. A caustic white deliquescent solid, KOH, used as a bleach and in the manufacture of soaps, dyes, alkaline batteries, and many potassium compounds. Also called caustic potash, lye, potash.

potassium hydroxide

n (Elements & Compounds) a white deliquescent alkaline solid used in the manufacture of soap, liquid shampoos, and detergents. Formula: KOH. Also called: caustic potash See also lye

potas′sium hydrox′ide

n. a white, deliquescent, water-soluble solid, KOH, that upon solution in water generates heat: used chiefly in the manufacture of soap, as a reagent, and as a caustic. [1880–85]

potassium hydroxide

A white, corrosive, solid compound, KOH, used in bleaches and to make soaps and detergents. It is soluble in water and very soluble in alcohol. In solution, it forms lye.

Translations

potassium hydroxide

potassium hydroxide,

chemical compound with formula KOH. Pure potassium hydroxide forms white, deliquescent crystals. For commercial and laboratory use it is usually in the form of white pellets. A strong base, it dissolves readily in water, giving off much heat and forming a strongly alkaline, caustic solution (see acids and basesacids and bases,
two related classes of chemicals; the members of each class have a number of common properties when dissolved in a solvent, usually water. Properties

It closely resembles sodium hydroxide in its chemical properties and has similar uses, e.g., in making soap, in bleaching, and in manufacturing chemicals, but is less widely used because of its higher cost. It is prepared chiefly by electrolysis of potassium chloride; commercial grades of it sometimes contain the chloride as well as other impurities.

Potassium Hydroxide

caustic potash, KOH, a strong alkali; colorless crystals. Density, 2.12 g/cm³ (25°C); melting point, 380°C.

Potassium hydroxide is readily soluble in water (97 g per 100 g H₂O at 0°C; 112 g at 20°C), liberating a considerable amount of heat. Potassium hydroxide is produced commercially in the form of an opaque solid white mass containing 90–92 percent KOH (representing a mixture of KOH and KOH·H₂O). In the air, potassium hydroxide absorbs H₂O and C0₂ and deliquesces, gradually converting to potassium carbonate K₂C0³. Potassium hydroxide has a destructive effect on skin, paper, wool, silk, and other organic materials; it causes severe burns on human skin and is particularly dangerous to the eyes. Safety goggles and rubber gloves must be worn when working with it. Potassium hydroxide is obtained by the electrolysis of calcium chloride solutions. Potassium hydroxide is used in the manufacture of liquid soaps, as a source material in the preparation of potassium salts, in alkaline batteries, and as a laboratory reagent.
