過硫酸鈉與水會發(fā)生反應(yīng)嗎?

過硫酸鈉的分子式為:NA2S2O8。肉眼一看,它是種白色無味的粉末。一般情況下它是非常穩(wěn)定的,但它“不耐熱”,受熱或者在潮濕的條件下它會快速分解。
The molecular formula of sodium persulfate is Na2S2O8. To the naked eye, it is a white tasteless powder. In general, it is very stable, but it is "heat-resistant", and it will decompose rapidly when heated or under humid conditions.
實驗表明,它能溶于水。溶于水時它會放出氧氣,不過其放氧速度比較緩慢。其溶于水的反應(yīng)式為:2 Na2S2O8 + 2 H2O = 2 Na2SO4 + 2 H2SO4 + O2↑ ,在這方程式中我們看到,過硫酸鈉溶于水時還產(chǎn)生了過硫酸根離子,這個離子大有用處,因為它有強氧化性,利用這一特性,過硫酸鈉可用作漂白劑、金屬表面處理劑、引發(fā)劑等等。
Experiments show that it can be dissolved in water. When dissolved in water, it will release oxygen, but its oxygen release rate is relatively slow. The reaction formula of dissolving in water is: 2 Na2S2O8 + 2 H2O = 2 Na2SO4 + 2 H2SO4 + O2 ↑. In this equation, we can see that sodium persulfate also produces persulfate ion when dissolving in water. This ion is very useful because it has strong oxidation. Using this characteristic, sodium persulfate can be used as bleach, metal surface treatment agent, initiator, etc.
過硫酸鈉
而過硫酸鹽可以產(chǎn)生自由基,這一反應(yīng)對于去除石油類污染物具有深遠的意義?!?/div>
Persulfate can activate the production of free radicals, which is of far-reaching significance for the removal of petroleum pollutants.]
可以說,水是過硫酸鈉的“貴人”,它們相互合作,各自發(fā)揮自己的特性,并產(chǎn)生良好的反應(yīng)結(jié)果。當然,這是從兩者的應(yīng)用上來說的,在過硫酸鈉儲存的角度而言,遇到水,過硫酸鈉就“倒霉”了。在儲存時必須保證儲存條件的干燥,并且更好存在在密閉的容器中,避免陽光直射,以免引起其分解。
It can be said that water is the "noble" of sodium persulfate. They cooperate with each other, give play to their own characteristics and produce good reaction results. Of course, this is from the application of both. From the perspective of sodium persulfate storage, sodium persulfate will be "unlucky" in case of water. During storage, the storage conditions must be dry, and it is best to store it in a closed container to avoid direct sunlight, so as not to cause its decomposition.
