氢氧化钾具有碱的通性!

发布来源:http://www.jinhao360.com    更新时间:2019-03-15 点击数:

  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 is alkaline, soluble in water and strongly corrosive. Dissolved in water gives off a lot of heat. Owing to the decomposition of carbohydrates by hydroxides, the risk of acid corrosion is more serious. The corroded skin usually presents deep burns and is difficult to heal. Once the eyes or skin contact, the injured part should be washed with water for more than 15 minutes, and immediately seek medical treatment. Oral treatment can burn the digestive tract, which can be fatal.
  氢氧化钾具有碱的通性,具有如下性质:
  Potassium hydroxide is alkaline 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: It can make litmus test solution blue and phenolphthalein test solution red.
  2、与酸反应:如与盐酸、硫酸、硝酸反应。
  2. Reaction with acids, such as hydrochloric acid, sulfuric acid and nitric acid.
  3、与酸性氧化物反应:如与二氧化碳、二氧化硫反应。
  3. Reaction with acid oxides, such as carbon dioxide and sulfur dioxide.
  4、与两性金属反应:如与铝反应。
  4. Reaction with amphoteric metals, such as aluminum.
氢氧化钾
  5、与两性氧化物反应:如与氧化铝反应。
  5. Reaction with amphoteric oxides, such as alumina.
  6、与两性氢氧化物反应。
  6. Reaction with amphoteric hydroxides.
  7、与过渡元素盐溶液发生复分解反应。
  7. Double decomposition reaction with transition element salt solution.
  除此之外,氢氧化钾还可以发生其他反应,如与白磷反应生成磷化氢气体,文中内容就是这种氢氧化物的通碱性质了,大家在以后的操作使用中,要多注意这方面的产品知识,防止误用和乱用。如果您有此类产品需求的话可以点击我们的官网进行咨询:http://www.jinhao360.com
  In addition, potassium hydroxide can also react with white phosphorus to produce phosphine gas. The content of this paper is the basic nature of this hydroxide. We should pay more attention to the product knowledge in the future operation and use, so as to prevent misuse and misuse.
