Potassium Hydroxide Solution (content ≥30%) is a colorless or slightly colored, transparent, viscous liquid at room temperature, with extremely strong corrosiveness. Its chemical properties are consistent with those of solid potassium hydroxide, characterized by extremely strong alkalinity: it can neutralize acids, react with amphoteric metals, and saponify fats and oils. The highly soluble potassium ions it provides typically result in the formation of potassium salts that are more soluble than their sodium counterparts. Based on this characteristic, its primary industrial applications are as a liquid strong alkali raw material. It is used in the production of high-purity liquid potassium soaps and high-quality alkaline battery electrolytes, serves as a carbon dioxide absorbent in chemical synthesis, and is widely employed as a strongly alkaline reaction medium and reagent in the fields of fine chemicals, pharmaceuticals, and chemical analysis.
