一般來說固體堿KOH或者NaOH只要密閉保存不受潮，就可以使用，不存在保質(zhì)期的問題。液體的KOH或者NaOH也是只要不因為水分蒸發(fā)而變成碳酸類物質(zhì)；沒有雜質(zhì)進入和堿液反應(yīng)，也是可以一直使用，沒有保質(zhì)期的問題。

Generally speaking, solid alkali KOH or NaOH can be used as long as it is sealed and stored without moisture, without any shelf life issues. The KOH or NaOH of liquid is also as long as it does not become carbonated substances due to water evaporation; No impurities enter and react with alkaline solution, and it can be used continuously without any shelf life issues.

NaOH密閉保存，有的3、5年都沒事。但是，固體KOH貌似要比固體NaOH就更容易受潮。有人反饋說，前幾天才發(fā)現(xiàn)：九個月前買的密封著的固體KOH，竟然受潮了。而且還把密封的塑料瓶給“燒”壞了。被“燒”壞的塑料瓶慘不忍睹。

NaOH is kept tightly sealed, and some will be fine for 3 to 5 years. However, solid KOH appears to be more susceptible to moisture than solid NaOH. Some people have reported that they discovered a few days ago that the sealed solid KOH they bought nine months ago was actually damp. And also burned the sealed plastic bottle. The plastic bottle that was burned out is unbearable.

裝固體KOH的塑料瓶的紙殼箱的一角留下了:受潮后生成的K2CO3與水的混合物。

A corner of the cardboard box containing solid KOH plastic bottles is left: a mixture of K2CO3 and water generated after being damp.

CO2+2KOH═K2CO3+H2O

CO2+2KOH═K2CO3+H2O

更神奇的是：K2CO3與水的混合物還擊穿了個紙殼箱，直接滲透到了第二個紙殼箱里，在第二個紙殼箱里留下了大量的水溶液?？胺Q大型車禍現(xiàn)場。足以看出KOH一旦受潮有多可怕了！

What's even more magical is that the mixture of K2CO3 and water also penetrated the first cardboard box and directly penetrated into the second cardboard box, leaving a large amount of aqueous solution in the second cardboard box. It can be considered a scene of a major car accident. It's enough to see how terrifying KOH can be once it gets damp!
