タイトルまたは説明

Potassium hydroxide, also known as caustic potash, is an inorganic compound with the chemical formula KOH. This chemical compound is commonly referred to as an inorganic base, and is known for its strong alkaline properties. A 0.1mol/L solution of this compound has a pH of *3.5, making it highly basic.

Potassium hydroxide is soluble in water and ethanol, but only slightly soluble in ether. This compound is highly hygroscopic and deliquescent; it easily absorbs water and carbon dioxide from the air. When potassium hydroxide absorbs carbon dioxide, it is converted into potassium carbonate.    

Application：
This compound has a wide range of uses, and is commonly used as a raw material for the production of potassium salt. Potassium hydroxide is commonly used to produce potassium permanganate, potassium carbonate, and other potassium-based salts.
 
Potassium hydroxide is also used in various industrial applications such as electroplating and printing and dyeing. The highly basic properties of this chemical compound make it an ideal candidate for these
applications.
 
One of the unique features of potassium hydroxide is its ability to react with fatty acids. This property makes it an essential ingredient in the production of soaps and detergents. Potassium hydroxide is known for its ability to break down fats and oils, making it an essential tool in the production of cleaning agents.
 
Another major application of potassium hydroxide is in the production of biodiesel. This chemical compound is used as a catalyst in the transesterification of vegetable oils and animal fats to produce biodiesel.
