我們在上中學(xué)的時候就學(xué)過可以使用堿性的物質(zhì)中和酸性溶液，那么氫氧化鉀自然也是可以用來中和的，但是其實我們在生活當(dāng)中還有一個經(jīng)常使用的就是石灰，用石灰進行中和的應(yīng)用是非常多的，那么大家可能就會有疑問了，在中和的時候兩者可以混合使用嗎。
When we were in middle school, we learned that we can use alkaline substances to neutralize acidic solutions. Naturally, potassium hydroxide can also be used to neutralize. But in fact, we often use lime in our life. There are many applications of lime for neutralization, so we may have doubts about whether the two can be mixed in neutralization.
廢水處理在進行中和反應(yīng)的時候一般都需要使用石灰，也稱為氫氧化鈣，它是一種白色或灰白色的粉末狀固體，因為它也是強堿性質(zhì)的，所以經(jīng)常被用于調(diào)節(jié)廢水PH值，當(dāng)然了在使用的時候還可以去除廢水當(dāng)中的磷酸鹽還有大部分重金屬，而且還可以起到殺 菌 消 毒的作用，一般在電鍍廠、化工廠、印染廠等地方也都有大量的使用。
Lime, also known as calcium hydroxide, is usually used in neutralization reaction of wastewater treatment. It is a white or grayish white powdery solid. Because it is also strongly alkaline, it is often used to adjust the pH value of wastewater. Of course, it can also remove phosphate and most heavy metals in wastewater, But also can play the role of sterilization, generally in electroplating plants, chemical plants, printing and dyeing plants and other places also have a lot of use.

因為在處理污水的行業(yè)里，廢水的水質(zhì)也是多種多樣的，所以在進行廢水處理的時候一般都會采用兩種或兩種以上的藥劑參與中和反應(yīng)，一般都會選擇化學(xué)性質(zhì)相同的藥劑添加進去進行處理。
Because in the wastewater treatment industry, the quality of wastewater is also diverse, so in wastewater treatment, generally two or more kinds of agents will be used to participate in the neutralization reaction, and generally the chemicals with the same chemical properties will be added for treatment.
比如在進行廢水處理的時候需要使用的片堿，就是一種白色半透明片狀物，同樣也是具有強堿性的和強腐蝕性的，而且氫氧化鉀也是比較容易吸水受潮的。所以在進行廢水處理的時候可以用于調(diào)節(jié)水中PH值。一般來說雖然在進行酸堿中和的時候可以選擇使用兩種藥劑配合使用的，不過在配合使用的時候值得注意的是需要控制好相應(yīng)的比例。
For example, the flake alkali used in wastewater treatment is a kind of white translucent flake, which is also strongly alkaline and corrosive, and potassium hydroxide is relatively easy to absorb water and get damp. Therefore, it can be used to adjust the pH value of water during wastewater treatment. Generally speaking, although in the acid-base neutralization, you can choose to use two kinds of chemicals in combination, but it is worth noting that you need to control the corresponding proportion.
看過上面的介紹，我們了解到在進行中和反應(yīng)的時候氫氧化鉀是可以和石灰混合使用的，不過因為兩者在性質(zhì)上還是有一些不同的，所以在混合的時候一定要控制好比例。
After reading the above introduction, we know that potassium hydroxide can be mixed with lime in neutralization reaction. However, there are some differences between the two in nature, so we must control the proportion when mixing.
