一般来说固体碱KOH或者NaOH只要密闭保存不受潮，就可以使用，不存在保质期的问题。液体的KOH或者NaOH也是只要不因为水分蒸发而变成碳酸类物质；没有杂质进入和碱液反应，也是可以一直使用，没有保质期的问题。

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密闭保存，有的3、5年都没事。但是，固体KOH貌似要比固体NaOH就更容易受潮。有人反馈说，前几天才发现：九个月前买的密封着的固体KOH，竟然受潮了。而且还把密封的塑料瓶给“烧”坏了。被“烧”坏的塑料瓶惨不忍睹。

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.

装固体KOH的塑料瓶的纸壳箱的一角留下了:受潮后生成的K2CO3与水的混合物。

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与水的混合物还击穿了第一个纸壳箱，直接渗透到了第二个纸壳箱里，在第二个纸壳箱里留下了大量的水溶液。堪称大型车祸现场。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!
