化工產(chǎn)品通常在生活中和行業(yè)生產(chǎn)中都有很重要地應(yīng)用,同時也充當(dāng)著不同的角色。當(dāng)其作為化學(xué)試劑時,它可以和很多其它類化學(xué)試劑發(fā)生反應(yīng),那么,它能與過氧化氫反應(yīng)嗎?具體分析如下。
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.
氫氧化鉀與過氧化氫這種物質(zhì)是能反應(yīng)的。過氧化氫有微弱的酸性,可以電離出氫離子。實際上雙氧水的一步電離較二步電離大得多的多。所以,它們之間的反應(yīng)是這樣的:
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:
KOH+H2O2=KHO2+H2O(中和一個氫離子)
Koh + H2O2 = kho2 + H2O (neutralize one hydrogen ion)
KHO2+KOH=KO2+H20(中和二個氫離子)
Kho2 + KOH = KO2 + H20 (neutralize two hydrogen ions)
4KO2+2H2O=4KOH+3O2(生成物與水之間的反應(yīng),放出氣體)
4ko2 + 2H2O = 4koh + 3O2 (reaction between product and water, release gas)
綜上所述,氫氧化鉀是能與過氧化氫發(fā)生反應(yīng)的,在此反應(yīng)中,氫氧化鉀即是反應(yīng)物又是生成物,也就是說,它起到了催化劑的作用,因此,后續(xù)如果往過氧化氫溶液中投入它的話,就能加速過氧化氫的分解,這一點催化作用也是可以在其它化學(xué)反應(yīng)中被充分利用的,希望你們能熟知。
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.
