Features & Chemical Properties

Chemical Formula: KOH
Appearance: Potassium hydroxide flakes are white to slightly yellow in color and have a crystalline structure.
Solubility: Potassium hydroxide is highly soluble in water, dissolving at a rate of 120 grams per 100 milliliters at 20°C.
Melting point: Potassium hydroxide melts at 360°C.
Boiling point: Potassium hydroxide boils at 1320°C.
pH: Potassium hydroxide has a pH of 11.5.
Thermal stability: Potassium hydroxide is highly thermally stable.
Hygroscopic: Potassium hydroxide absorbs moisture from the air and becomes sticky when exposed to it.
Toxicity: Potassium hydroxide is highly toxic and can cause irritation to the skin, eyes, and nose. Swallowing small amounts of potassium hydroxide can cause acute poisoning and be life-threatening.
Storage: Potassium hydroxide should be stored in a dry place with intact packaging and kept separate from acids, explosives, and other chemicals.

Applications

Many potassium salts are prepared by neutralization reactions involving KOH.

Potassium hydroxide to make other potassium compounds

Although more expensive than using sodium hydroxide, KOH works well in the manufacture of biodiesel by saponification of the fats in vegetable oil.

Biodiesel manufacture

Potassium hydroxide used in the manufacture of soft soaps. The saponification of fats with KOH is used to prepare the corresponding “potassium soaps” which are softer than the more common sodium hydroxide-derived soaps.

Making Soap from Potassium hydroxide

Aqueous potassium hydroxide is employed as the electrolyte in alkaline batteries based on nickel-cadmium and manganese dioxide-zinc.

Potassium hydroxide as an electrolyte

KOH attracts numerous specialized applications, which virtually all rely on its basic or degradative properties. KOH is widely used in the laboratory for the same purposes.
