氢氧化钾,是一种没有机化合物,化学式为KOH,是常见的没有机碱,具有强碱性,0.1mol/L溶液的pH为13.5,溶于水、乙醇,微溶于乙醚,极易吸收空气中水分而潮解,吸收二氧化碳而成碳酸钾,主要用作生产钾盐的原料,也可用于电镀、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.
氢氧化钾外观为白色片状或粉状,具有强烈腐蚀性和强碱性。氢氧化钾暴露在空气中时,易被空气中的水分而潮解,并吸收二氧化碳而成碳酸钾。易溶于水、乙醇或酸,并释放大量的热量。
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.
氢氧化钾溶解度在不同温度下,溶解度也有所不同。在0℃时,能溶解97克氢氧化钾;在10℃时,能溶解103克氢氧化钾;在20℃时,能溶解112克氢氧化钾;在30℃时,能溶解126克氢氧化钾。由此可见,温度高时,氢氧化钾的溶解度也提高了。
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.
氢氧化钾对组织有烧灼作用,可溶解蛋白质,形成碱性变性蛋白质。溶液或粉尘溅到皮肤上,尤其溅到黏膜,可产生软痂。氢氧化钾的溶解度溶越高,温度越高,作用就越强。如不慎溅入眼内,不仅可损伤角膜,而且能使眼部深组织损伤。
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.
氢氧化钾较高容许浓度为0.5mg/m。工作时应防止触及皮肤和眼睛,如不慎触及时,可用流水洗涤受损部位,然后湿敷5%的醋酸、酒石酸、盐酸或柠檬酸溶液;如溅人眼内,应用流水或生理盐水仔细缓慢洗涤10~30min,然后点入2%的奴佛卡因或0.5%的地卡因溶液。更多相关事项就来我们网站

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.
