氢氧化钾能与过氧化氢反应吗?

发布来源:http://www.jinhao360.com    更新时间:2020-05-20 点击数:

化工产品通常在生活中和行业生产中都有很重要地应用,同时也充当着不同的角色。当其作为化学试剂时,它可以和很多其它类化学试剂发生反应,那么,它能与过氧化氢反应吗?具体分析如下。

Chemical products are often used in life and industry production, and also play different roles. When it is used as a chemical reagent, it can react with many other chemical reagents. So, can it react with hydrogen peroxide? The specific analysis is as follows.
氢氧化钾与过氧化氢这种物质是能反应的。过氧化氢有微弱的酸性,可以电离出氢离子。实际上双氧水的一步电离较二步电离大得多的多。所以,它们之间的反应是这样的:
Potassium hydroxide can react with hydrogen peroxide. Hydrogen peroxide has weak acidity and can ionize hydrogen ions. In fact, the one-step ionization of hydrogen peroxide is much larger than the two-step ionization. So the reaction between them is like this:
氢氧化钾
KOH+H2O2=KHO2+H2O(中和一个氢离子)
Koh + H2O2 = kho2 + H2O (neutralize one hydrogen ion)
KHO2+KOH=KO2+H20(中和二个氢离子)
Kho2 + KOH = KO2 + H20 (neutralize two hydrogen ions)
4KO2+2H2O=4KOH+3O2(生成物与水之间的反应,放出气体)
4ko2 + 2H2O = 4koh + 3O2 (reaction between product and water, release gas)
综上所述,氢氧化钾是能与过氧化氢发生反应的,在此反应中,氢氧化钾即是反应物又是生成物,也就是说,它起到了催化剂的作用,因此,后续如果往过氧化氢溶液中投入它的话,就能加速过氧化氢的分解,这一点催化作用也是可以在其它化学反应中被充分利用的,希望你们能熟知。
To sum up, potassium hydroxide can react with hydrogen peroxide. In this reaction, potassium hydroxide is both the reactant and the product, that is to say, it plays the role of catalyst. Therefore, if it is put into hydrogen peroxide solution later, it can accelerate the decomposition of hydrogen peroxide, which can also be fully utilized in other chemical reactions Yes, I hope you know it well.
