　　氢氧化钾是白色粉末或颗粒状固体，无臭无味，易溶于水，水溶液呈弱碱性反应（ph值约为9-10）。溶于甲醇、乙醇和丙酮等有机溶剂。

Potassium hydroxide is a white powder or granular solid, odorless and tasteless, easily soluble in water. The aqueous solution exhibits a weak alkaline reaction (pH value is about 9-10). Soluble in organic solvents such as methanol, ethanol, and acetone.

　　其水溶液具有吸湿性，加热会分解并产生氨气与二氧化碳气体。有潮解性且吸湿性强。稳定性好于苛性钠（koh），但低于硫酸铝（na2s04）、三氧化硫（so3）。不溶于液氨及甘油而不发生沉淀现象。

Its aqueous solution has hygroscopicity, and heating will decompose and produce ammonia and carbon dioxide gases. Has deliquescence and strong moisture absorption. Stability is better than caustic soda (koh), but lower than aluminum sulfate (na2s04) and sulfur trioxide (so3). Insoluble in liquid ammonia and glycerol without precipitation.
