Description of hydroxydedepotassium
- Potassium hydroxide is an inorganic compound with the formula KOH, and is commonly called caustic potash.
Along with sodium hydroxide (NaOH), this colorless solid is a prototypical strong base. It has many industrial and niche applications, most of which exploit its corrosive nature and its reactivity toward acids. An estimated 700,000 to 800,000 tonnes were produced in 2005. Approximately 100 times more NaOH than KOH is produced annually. KOH is noteworthy as the precursor to most soft and liquid soaps as well as numerous potassium-containing chemicals.

What is Potassium hydroxide?
- With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Potassium hydroxide which has developed particularly rapidly in recent years. Do you know about Potassium hydroxide?
- The official answer:Potassium hydroxide is commonly known as caustic potash, potassium ash, etc. There are two main forms of industrial products, solid and liquid, of which the solid is a white or light gray flake or stick, and the liquid potassium hydroxide is a light yellow liquid. It is chemically similar to sodium hydroxide, highly alkaline and corrosive, easily soluble in water and exothermic, and deliquescent, easily absorbing moisture in the air and becoming potassium carbonate by absorbing carbon dioxide. Generates a lot of heat when dissolved in water, alcohol, or treated with acid. the pH of 0.1 mol/L solutions is 13.5. (anhydrous). Moderately toxic, LD50 (rat, oral) 1230 mg/kg. currently, potassium hydroxide is mainly used to synthesize potassium carbonate, potassium permanganate, etc., which are mainly used in many fields such as chemical, food, medicine, and agriculture.
What’s the application of Potassium hydroxide?
- Used as a desiccant, absorbent, for the production of potassium soap, oxalic acid, and various potassium salts, also used in electroplating, engraving, lithography, etc. Mainly used as raw materials for the production of potassium salts, such as potassium permanganate, potassium carbonate, etc. In the pharmaceutical industry, used in the production of potassium borohydride, anisodone, salvianolic, progesterone and testosterone propionate, etc. In the light industry, it is used in the production of potassium soap, alkaline batteries, cosmetics (such as cold cream, snow cream, and shampoo). In the dye industry, it is used to produce reduction dyes, such as reduction blue RSN, etc. In the electrochemical industry, it is used for electroplating, engraving, etc. In the textile industry, used in printing and dyeing, bleaching, and mercerizing, and a large number of users as the main raw material for the manufacture of man-made fibers, polyester fibers. In addition, it is also used in a metallurgical heating agent and leather degreasing, etc. Uses chemical basic raw materials, used in medicine, daily-use chemicals, etc. Used as analytical reagent, saponification reagent, carbon dioxide, and water absorber, also used in the pharmaceutical industry acid-base neutralization to adjust the pH value of the solution. Basic chemical reagent, carbon dioxide absorber. Saponification agent.
