氢氧化钾在购买的时候价格和其他的碱性产品相比来说都会高一些，这也是因为其本身具有的性能是非常好的，比如在很多的洗护用品当中都需要使用到它，在当中起到主要清洁的作用并且不会对皮肤产生伤害，但是其实因为其本身仍然是属于碱性的，所以在进行存放的时候也是也可能会出现变质情况的，那么我们在进行使用的时候应该怎么去辨别它有没有变质呢？

Potassium hydroxide has a higher price compared to other alkaline products when purchased, which is also because its inherent performance is very good. For example, it needs to be used in many cleaning products to play a main cleaning role and not cause harm to the skin. However, in fact, it is still alkaline, So there may also be deterioration during storage, so how should we distinguish whether it has deteriorated during use?

1、我们都知道碱性物质和酸性物质混合在一起的时候会进行中和反应，而这两者在进行反应的过程当中是会产生盐和水的，可是如果是变质的和酸性物质进行反映的是会有气泡产生的，这种方法可以排除出来产品有没有变质

1. We all know that when alkaline and acidic substances are mixed together, they undergo a neutralization reaction, and during the reaction, salt and water are produced. However, if the reaction is between spoiled and acidic substances, bubbles will be generated. This method can rule out whether the product has deteriorated or not

2、还可以将氯化钡溶液添加到产品当中进行搅拌，如果在搅拌之后出现沉淀物那么就表示氢氧化钾已经变质。

2. Barium chloride solution can also be added to the product for stirring. If sediment appears after stirring, it indicates that potassium hydroxide has deteriorated.

3、还可以先准备一杯已经饱和的片碱溶液，然后再将需要检测的产品添加进去如果仍然可以溶解进去，那么说明这个溶解进去的可能是其他的物质了，如果无法溶解进去依然以沉淀的状态存在的时候那么一般出现变质的可能性会小一些。

3. You can also prepare a cup of saturated flake alkali solution first, and then add the product to be tested. If it can still be dissolved, it indicates that the dissolved substance may be other substances. If it cannot be dissolved and still exists in a precipitated state, the likelihood of deterioration is generally lower.

上面介绍的就是判断氢氧化钾有没有变质的几种方法，其实很多的碱性物质在进行使用的时候即便是出现了变质也是不影响使用的，但是该产品因为比较广泛的应用在很多的洗护用品当中，所以在进行使用的时候如果出现了变质的情况是非常影响正常使用的，甚至可能会导致产品在进行使用的时候对皮肤产生一定的伤害，所以要多加注意，更多事项就来我们网站http://qxu1539600089.my3w.com咨询吧!

The above introduces several methods for determining whether potassium hydroxide has deteriorated. In fact, many alkaline substances do not affect their use even if they have deteriorated during use. However, due to its wide application in many toiletries, if there is any deterioration during use, it can greatly affect normal use, It may even cause certain skin damage when using the product, so it is important to pay more attention and visit our website for more details http://qxu1539600089.my3w.com Consult!
