氫氧化鉀在購買的時候和其他的堿性產品相比來說都會高一些，這也是因為其本身具有的性能是非常好的，比如在很多的洗護用品當中都需要使用到它，在當中起到主要清潔的作用并且不會對皮膚產生傷害，但是其實因為其本身仍然是屬于堿性的，所以在進行存放的時候也是也可能會出現(xiàn)變質情況的，那么我們在進行使用的時候應該怎么去辨別它有沒有變質呢？

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、我們都知道堿性物質和酸性物質混合在一起的時候會進行中和反應，而這兩者在進行反應的過程當中是會產生鹽和水的，可是如果是變質的和酸性物質進行反映的是會有氣泡產生的，這種方法可以排除出來產品有沒有變質

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、還可以將氯化鋇溶液添加到產品當中進行攪拌，如果在攪拌之后出現(xiàn)沉淀物那么就表示氫氧化鉀已經變質。

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、還可以先準備一杯已經飽和的片堿溶液，然后再將需要檢測的產品添加進去如果仍然可以溶解進去，那么說明這個溶解進去的可能是其他的物質了，如果無法溶解進去依然以沉淀的狀態(tài)存在的時候那么一般出現(xiàn)變質的可能性會小一些。

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.

上面介紹的就是判斷氫氧化鉀有沒有變質的幾種方法，其實很多的堿性物質在進行使用的時候即便是出現(xiàn)了變質也是不影響使用的，但是該產品因為比較廣泛的應用在很多的洗護用品當中，所以在進行使用的時候如果出現(xiàn)了變質的情況是非常影響正常使用的，甚可能會導致產品在進行使用的時候對皮膚產生一定的傷害，所以要多加注意，更多事項就來我們網站http://www.tjxjw.com咨詢吧!

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://www.tjxjw.com Consult!
