在中和时氢氧化钾与石灰可以混用吗?

发布来源:http://www.jinhao360.com    更新时间:2021-05-06 点击数:

我们在上中学的时候就学过可以使用碱性的物质中和酸性溶液,那么氢氧化钾自然也是可以用来中和的,但是其实我们在生活当中还有一个经常使用的就是石灰,用石灰进行中和的应用是非常多的,那么大家可能就会有疑问了,在中和的时候两者可以混合使用吗。

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.
废水处理在进行中和反应的时候一般都需要使用石灰,也称为氢氧化钙,它是一种白色或灰白色的粉末状固体,因为它也是强碱性质的,所以经常被用于调节废水PH值,当然了在使用的时候还可以去除废水当中的磷酸盐还有大部分重金属,而且还可以起到杀 菌 消 毒的作用,一般在电镀厂、化工厂、印染厂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.
因为在处理污水的行业里,废水的水质也是多种多样的,所以在进行废水处理的时候一般都会采用两种或两种以上的药剂参与中和反应,一般都会选择化学性质相同的药剂添加进去进行处理。
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.
比如在进行废水处理的时候需要使用的片碱,就是一种白色半透明片状物,同样也是具有强碱性的和强腐蚀性的,而且氢氧化钾也是比较容易吸水受潮的。所以在进行废水处理的时候可以用于调节水中PH值。一般来说虽然在进行酸碱中和的时候可以选择使用两种药剂配合使用的,不过在配合使用的时候值得注意的是需要控制好相应的比例。
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.
看过上面的介绍,我们了解到在进行中和反应的时候氢氧化钾是可以和石灰混合使用的,不过因为两者在性质上还是有一些不同的,所以在混合的时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.
