氢氧化钾具有碱的通性,易溶于水,有强烈腐蚀性。溶于水放出大量热。并且由于氢氧化物对碳水化合物的分解作用,而使其相对于酸腐蚀的危险更加严重,经腐蚀的皮肤,通常呈现深度灼伤,且难以愈合,一旦眼睛或皮肤接触到,应迅速将受伤部位以水不断冲洗15分钟以上,并立即就医;口服会灼伤消化道,可致命。
Potassium hydroxide has the general property of alkali, is easily soluble in water, and is highly corrosive. Dissolve in water and release a large amount of heat. Moreover, due to the Decomposition effect of hydroxide on carbohydrates, the risk of hydroxide corrosion is more serious than that of acid corrosion. The corroded skin usually shows deep burns and is difficult to heal. Once the eyes or skin contact it, the injured part should be quickly washed with water for more than 15 minutes, and immediately seek medical advice; Oral administration can burn the digestive tract and can be fatal.
氢氧化钾具有碱的通性,具有如下性质:
Potassium hydroxide has the general property of alkali and has the following properties:
1、碱性反应:可使石蕊试液变蓝、酚酞试液变红。
1. Alkaline reaction: can turn litmus test solution blue and phenolphthalein test solution red.

In addition, potassium hydroxide can also undergo other reactions, such as reacting with white phosphorus to generate Phosphine gas. The content in this article is about the alkali passing property of this hydroxide. In the future operation, we should pay more attention to product knowledge in this regard to prevent misuse and misuse.
