要看一种物质是氧化还是还原性,关键在于它所含粒子的情况。在氢氧化钾中,钾有+ 1价,所以它只能得到一个电子被还原,所以它在氧化。答案中有个缺陷,oh没有氧化或还原。为什么?因为所谓的电解什么的并不是一个真正的反应过程,例如,硅与氢氧化钠反应,方程式是氢氧化钠和氢氧化氧化,但氧化剂是水,反应是误导,因为这两个虱子都写在一起。记住,一般来说,当你得到高的正价时,你只显示氧化,当你得到低的负价时,你只显示还原。
To see whether a substance is redox or redox, the key lies in the case of the particles it contains. In potassium hydroxide, potassium has a + 1 valence, so it can only get one electron to be reduced, so it is oxidized. One drawback of the answer is that Oh is not oxidized or reduced. Why? Because what is called electrolysis is not a real reaction process, for example, the reaction of silicon with sodium hydroxide. The equation is sodium hydroxide and hydroxide oxidation, but the oxidant is water. The reaction is misleading, because both lice are written together. Remember, generally speaking, when you get the highest positive valence, you only show oxidation, and when you get the lowest negative valence, you only show reduction.
臭氧与氢氧化钾的反应是4KOH+4O3+2H2O=4KO3·H2O+O2
The reaction between ozone and potassium hydroxide is 4KOH+4O 3+2H 2=4KO 3.H 2+O 2.
的原因是臭氧氧化的反应很强,有一定的还原性和KOH,反应会产生两个橙红色固体KO3·H2O一水臭卡莉,称为“臭卡莉】【,O3是减少O2和O3 -氧气】【】【臭氧根,和原来的氧化态,二也是O3氧化的氧-(部分)。
The reason is that the ozone oxidation reaction is very strong, with certain reductivity and KOH. The reaction produces two orange-red solid KO 3 H 2 2 O 3
反应的本质是臭氧的氧化——氧的氧化态,结果O3的形成和氧气,但电子的总数在O3 – 23,顺,容易分解,在稀溶液将很快分解成氧气和KOH,如果它是一个稀溶液,反应产物是氧气,KOH保持不变。在浓缩液中,KO3·H2O析出为橙红色固体,然后缓慢分解为KO2[过氧化物钾]和O2
The essence of the reaction is the oxidation of ozone – the oxidation state of oxygen, resulting in the formation of O3 and oxygen, but the total number of electrons in O3 – 23, cis, easy to decompose, in dilute solution will soon decompose into oxygen and KOH, if it is a dilute solution, the reaction product is oxygen, KOH remains unchanged. In the concentrated solution, KO_3 H_2 precipitates into orange solid, then slowly decomposes into KO_2 [potassium peroxide] and O_2.
结论:臭氧与氢氧化钾反应生成氧化钾和氧。如果溶液很薄,产物就是氧。
Conclusion: Ozone reacts with potassium hydroxide to produce potassium oxide and oxygen. If the solution is very thin, the product is oxygen.
注:该反应也适用于氢氧化铷和氢氧化铯,但不适用于氢氧化钠,因为臭氧化钠稳定性低,可立即分解为氧和氢氧化钠。
Note: This reaction is also applicable to rubidium hydroxide and cesium hydroxide, but not to sodium hydroxide, because the stability of sodium ozonate is low, it can be immediately decomposed into oxygen and sodium hydroxide.
