氫氧化鉀，是一種沒有機化合物，化學式為KOH，是常見的沒有機堿，具有強堿性，0.1mol/L溶液的pH為13.5，溶于水、乙醇，微溶于乙醚，極易吸收空氣中水分而潮解，吸收二氧化碳而成碳酸鉀，主要用作生產鉀鹽的原料，也可用于電鍍、印染等。

Potassium hydroxide is a non organic compound with the chemical formula KOH. It is a common non organic alkali and has strong alkalinity. The pH of a 0.1mol/L solution is 13.5, soluble in water and ethanol, slightly soluble in ether, and easily absorbs moisture from the air and deliquests. It absorbs carbon dioxide to form potassium carbonate. It is mainly used as a raw material for the production of potassium salts and can also be used in electroplating, printing and dyeing, etc.

氫氧化鉀外觀為白色片狀或粉狀，具有強烈腐蝕性和強堿性。氫氧化鉀暴露在空氣中時，易被空氣中的水分而潮解，并吸收二氧化碳而成碳酸鉀。易溶于水、乙醇或酸，并釋放大量的熱量。

Potassium hydroxide appears as a white flake or powder, with strong corrosiveness and alkalinity. When potassium hydroxide is exposed to the air, it is easily deliquescent by the moisture in the air and absorbs carbon dioxide to form potassium carbonate. Easily soluble in water, ethanol, or acid, and releases a large amount of heat.

氫氧化鉀溶解度在不同溫度下，溶解度也有所不同。在0℃時，能溶解97克氫氧化鉀;在10℃時，能溶解103克氫氧化鉀;在20℃時，能溶解112克氫氧化鉀;在30℃時，能溶解126克氫氧化鉀。由此可見，溫度高時，氫氧化鉀的溶解度也提高了。

The solubility of potassium hydroxide varies at different temperatures. At 0 ℃, 97 grams of potassium hydroxide can be dissolved; At 10 ℃, it can dissolve 103 grams of potassium hydroxide; At 20 ℃, it can dissolve 112 grams of potassium hydroxide; At 30 ℃, 126 grams of potassium hydroxide can be dissolved. It can be seen that at high temperatures, the solubility of potassium hydroxide also increases.

氫氧化鉀對組織有燒灼作用，可溶解蛋白質，形成堿性變性蛋白質。溶液或粉塵濺到皮膚上，尤其濺到黏膜，可產生軟痂。氫氧化鉀的溶解度溶越高，溫度越高，作用就越強。如不慎濺入眼內，不僅可損傷角膜，而且能使眼部深組織損傷。

Potassium hydroxide has a burning effect on tissues, which can dissolve proteins and form alkaline denatured proteins. Solution or dust splashing on the skin, especially on the mucous membrane, can produce soft scabs. The higher the solubility and temperature of potassium hydroxide, the stronger its effect. If accidentally splashed into the eye, it can not only damage the cornea, but also cause deep tissue damage to the eye.

氫氧化鉀較高容許濃度為0.5mg/m。工作時應防止觸及皮膚和眼睛，如不慎觸及時，可用流水洗滌受損部位，然后濕敷5%的醋酸、酒石酸、鹽酸或檸檬酸溶液;如濺人眼內，應用流水或生理鹽水仔細緩慢洗滌10～30min，然后點入2%的奴佛卡因或0.5%的地卡因溶液。更多相關事項就來我們網站http://www.shrisa.cn咨詢！

The higher allowable concentration of potassium hydroxide is 0.5mg/m. During work, it is necessary to prevent contact with the skin and eyes. If accidentally touched in a timely manner, the damaged area can be washed with running water, and then wet applied with 5% acetic acid, tartaric acid, hydrochloric acid or citric acid solution; If splashing into the eyes, wash carefully and slowly with running water or physiological saline for 10 to 30 minutes, and then add 2% novocaine or 0.5% dicaine solution.
