Compared with other alkaline products, the price of potassium hydroxide is higher than that of other alkaline products. This is also because its performance is very good. For example, it needs to be used in many cleaning products. It plays a main role in cleaning and does not harm the skin. However, because it is still alkaline, it is in progress When it is stored, there may be deterioration, so how can we identify whether it has deteriorated or not when we use it.

1、我們都知道堿性物質(zhì)和酸性物質(zhì)混合在一起的時(shí)候會(huì)進(jìn)行中和反應(yīng)，而這兩者在進(jìn)行反應(yīng)的過程當(dāng)中是會(huì)產(chǎn)生鹽和水的，可是如果是變質(zhì)的和酸性物質(zhì)進(jìn)行反映的是會(huì)有氣泡產(chǎn)生的，這種方法可以排除出來產(chǎn)品有沒有變質(zhì)

1. We all know that alkaline substances and acidic substances will be neutralized when they are mixed together, and the two will produce salt and water during the reaction process. However, if it is deteriorated and acidic substances are reflected, there will be bubbles. This method can be used to exclude whether the product has deteriorated

2、還可以將氯化鋇溶液添加到產(chǎn)品當(dāng)中進(jìn)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(jīng)變質(zhì)。

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

3、還可以先準(zhǔn)備一杯已經(jīng)飽和的片堿溶液，然后再將需要檢測(cè)的產(chǎn)品添加進(jìn)去如果仍然可以溶解進(jìn)去，那么說明這個(gè)溶解進(jìn)去的可能是其他的物質(zhì)了，如果無法溶解進(jìn)去依然以沉淀的狀態(tài)存在的時(shí)候那么一般出現(xiàn)變質(zhì)的可能性會(huì)小一些。

3. You can also prepare a cup of saturated caustic soda solution, and then add the product to be tested. If it can still be dissolved in, it means that other substances may be dissolved in it. If it can not be dissolved in and still exists in the precipitation state, the possibility of deterioration will be less.

上面介紹的就是判斷氫氧化鉀有沒有變質(zhì)的幾種方法，其實(shí)很多的堿性物質(zhì)在進(jìn)行使用的時(shí)候即便是出現(xiàn)了變質(zhì)也是不影響使用的，但是該產(chǎn)品因?yàn)楸容^廣泛的應(yīng)用在很多的洗護(hù)用品當(dāng)中，所以在進(jìn)行使用的時(shí)候如果出現(xiàn)了變質(zhì)的情況是非常影響正常使用的，甚可能會(huì)導(dǎo)致產(chǎn)品在進(jìn)行使用的時(shí)候?qū)ζつw產(chǎn)生一定的傷害。

The above is to judge whether potassium hydroxide has deteriorated several methods. In fact, many alkaline substances will not affect the use even when they are used. However, the product is widely used in many cleaning products, so if the deterioration occurs during the use, it will affect the normal use, even It may cause certain damage to the skin when the product is used.
