氫氧化鉀是白色粉末狀或固體狀產(chǎn)品,是常用的化工原料。而產(chǎn)品在保存過(guò)程中了解產(chǎn)品的性質(zhì)尤其是否具備易潮解性是很重要的,關(guān)系到產(chǎn)品儲(chǔ)存方式,以下是這方便的詳細(xì)介紹。
Potassium hydroxide is a white powder or solid product, which is a common chemical raw material. It is very important to know the nature of the product, especially whether it is deliquescent, during the storage process of the product. It is related to the storage method of the product. The following is a convenient and detailed introduction.
氫氧化鉀暴露于空氣中時(shí),易吸收二氧化碳和水分,逐漸變成碳酸鉀。易溶于水,溶解時(shí)會(huì)放出大量的溶解熱,有很強(qiáng)的吸水性,在空氣中能吸收水分而被溶解,并吸收二氧化碳逐漸變成碳酸鉀。溶于乙醇,微溶于醚。有強(qiáng)的堿性和腐蝕性,其性質(zhì)與燒堿相似。能引起灼傷,易于吸收空氣中的水分和CO2。
When potassium hydroxide is exposed to the air, it is easy to absorb carbon dioxide and water, and gradually becomes potassium carbonate. It is easy to dissolve in water. When it is dissolved, it will emit a lot of heat of dissolution. It has strong water absorption. It can absorb water in the air and be dissolved, and absorb carbon dioxide and gradually become potassium carbonate. Soluble in ethanol, slightly soluble in ether. It has strong alkalinity and corrosivity, and its property is similar to that of caustic soda. It can cause burns and easily absorb moisture and CO2 in the air.
氫氧化鉀具有堿的性質(zhì):
Potassium hydroxide has alkaline properties:
1.氫氧化鉀與堿反應(yīng)可使石蕊試液變藍(lán),酚酞試液變紅。
1. The reaction of potassium hydroxide with alkali can make litmus test solution turn blue and phenolphthalein test solution turn red.
2.氫氧化鉀與鹽酸的反應(yīng):KOH+HCl=KCl+HO;
2. Reaction of potassium hydroxide and hydrochloric acid: KOH+HCl=KCl+HO;
3.與***反應(yīng):2koh+HSO=kso+2ho;
3. Reaction with * * *: 2koh+HSO=kso+2ho;
4.與硝酸反應(yīng):KOH+HNO=KNO+HO;
4. Reaction with nitric acid: KOH+HNO=KNO+HO;
5.與二氧化碳反應(yīng):2koh+co=kco+ho;
5. Reaction with carbon dioxide: 2koh+co=kco+ho;
6.與二氧化硫的反應(yīng):2koh+so=kso+ho。
6. Reaction with sulfur dioxide: 2koh+so=kso+ho.
通過(guò)上述不難看出氫氧化鉀是比較活躍的化學(xué)產(chǎn)品,在保存過(guò)程中要做好密封措施,采用的包裝材料,避免因受潮影響產(chǎn)品純度。更多相關(guān)內(nèi)容就來(lái)我們網(wǎng)站

It is not difficult to see from the above that potassium hydroxide is a relatively active chemical product. During storage, sealing measures should be taken and professional packaging materials should be used to avoid affecting the purity of the product due to moisture.
