氫氧化鉀穩定性好，水溶性好，氧化性比較強，可以說優點還是比較多的，大家對氫氧化鉀的成分了解多少，可以說氫氧化鉀的用處也是比較大的！

Potassium hydroxide has good stability, good water solubility and strong oxidizability. It can be said that it has many advantages. How much do you know about the composition of potassium hydroxide? It can be said that potassium hydroxide is also quite useful!

分子式為KOH，白色晶體。飽和蒸氣壓(kPa)：0.13(719℃)。溶于水、乙醇，微溶于醚。易潮解并吸收二氧化碳。其化學性質相似氫氧化鈉（燒堿），水溶液呈強堿性，能毀壞細胞組織。

The molecular formula is KOH, white crystal. Saturated vapor pressure (kPa): 0.13 (719 ℃). Soluble in water and ethanol, slightly soluble in ether. It is easy to deliquescence and absorb carbon dioxide. Its chemical properties are similar to sodium hydroxide (caustic soda), and its aqueous solution is strongly alkaline, which can destroy cell tissue.

有4分子水的水合物。固體氫氧化鉀遇水或水蒸氣產生熱量，會使易燃物質到達熄滅溫度，故應置于枯燥場所儲存。可使石蕊試液變藍、酚酞試液變紅。

Hydrate with 4 molecules of water. Solid potassium hydroxide generates heat when it meets water or water vapor, which will make flammable substances reach the extinction temperature, so it should be stored in a dry place. It can make litmus test solution turn blue and phenolphthalein test solution turn red.

如與、硫酸、反響。如與二氧化碳、二氧化硫反響。如與鋁反響。如與氧化鋁反響。除此之外，氫氧化鉀還能夠發作其他反響，如與白磷反響生成氣體。

Such as and, sulfuric acid, reaction. Such as reaction with carbon dioxide and sulfur dioxide. Such as the reaction with aluminum. Such as reaction with alumina. In addition, potassium hydroxide can also produce other reactions, such as reacting with white phosphorus to generate gas.

無機工業用作消費鉀鹽，如、亞、磷酸氫二鉀等的原料。日化工業用作制造鉀肥皂、洗污肥皂、洗頭軟皂、雪花膏、冷霜、洗發膏等的原料。工業用于制造、香蘭素等原料。

Inorganic industry is used as raw material for consumption of potassium salts, such as potassium bisulfite and potassium hydrogen phosphate. The daily chemical industry is used as the raw material for manufacturing potassium soap, detergent soap, shampoo soap, cream, cold cream, shampoo, etc. Industrial use for manufacturing, vanillin and other raw materials.

通過上面大家是不是感覺氫氧化鉀的用處是比較大的，可以適用到各個行業，可以說氫氧化鉀給我們生活也帶來了方便，在我們生活當中起著很重要的作用，希望上面的一些內容可以幫助到大家要是還想了解更多的相關知識可以繼續關注我們http://m.yiqijieneng.cn。

From the above, do you feel that potassium hydroxide is of great use and can be applied to all industries? It can be said that potassium hydroxide has brought convenience to our lives and played a very important role in our lives.
