因為氫氧化鉀比氫氧化鈉難脫水，市售品的純度一般只能達到85%～86%。如需提純可按照提純氫氧化鈉的相同的方法進行提純。氫氧化鉀經精制后，預熱，不斷注入電解槽中，電解生成液經濃縮、脫色而得。

Because potassium hydroxide is more difficult to dehydrate than sodium hydroxide, the purity of commercially available products can only reach 85% ~ 86%. If purification is required, it can be purified according to the same method of purifying sodium hydroxide. Potassium hydroxide is refined, preheated and continuously injected into the electrolytic cell. The electrolytic generated solution is obtained by concentrating and decolorizing.

氫氧化鉀溶于水時放出大量的熱，很難測得大于30℃時的溶解度（氫氧化鈉也是這樣），如果說乙酸不算固體，那給舉個其它的例子，SbCl3在0℃時溶解度是601.6克，60℃時溶解度是4531克，80℃時是無窮大。確實如此，一滴水就能改變分子間的力，使它從固態變為液態。即使是水解，它也是在水中溶解了。

When potassium hydroxide is dissolved in water, it gives off a lot of heat, so it is difficult to measure the solubility greater than 30 ℃ (the same is true for sodium hydroxide). If acetic acid is not a solid, give another example. The solubility of SbCl3 is 601.6g at 0 ℃, 4531g at 60 ℃ and infinity at 80 ℃. Indeed, a drop of water can change the force between molecules from solid to liquid. Even if it is hydrolyzed, it is dissolved in water.

由于氫氧化鉀溶解于水會釋放出大量的熱量，濃氫氧化鉀也具有強烈的腐蝕性。溶解氫氧化鉀時應將氫氧化鉀加入到水中。先將一定量的水加入到燒杯中，再慢慢地將稱好的氫氧化鉀一點點加入水中，并不斷攪拌，使其加速溶解，而且氫氧化鉀溶解時要放出大量的熱量，攪拌可使溶液溫度均勻。

As potassium hydroxide dissolves in water, it will release a lot of heat, and concentrated potassium hydroxide also has strong corrosivity. When dissolving potassium hydroxide, potassium hydroxide shall be added to water. First add a certain amount of water to the beaker, then slowly add the weighed potassium hydroxide to the water a little, and keep stirring to accelerate the dissolution. Moreover, a large amount of heat should be released when the potassium hydroxide is dissolved. Stirring can make the solution temperature uniform.

此外是鉀一旦成為化合物，堿的堿性強弱與堿的電離程度有關。肥皂、堿性就越大金屬活潑順序表里鉀在鈉前面前面都是氫氧，所以氫氧化鉀的堿性要比氫氧化鈉的堿性大哦！

In addition, once potassium becomes a compound, the alkalinity of the base is related to the ionization degree of the base. The greater the soap and alkalinity, the more active the metal is. In the table, potassium is hydrogen and oxygen in front of sodium, so the alkalinity of potassium hydroxide is greater than that of sodium hydroxide!

金屬活動性順序是鉀鈉鉀的氧化性更強，氫氧化鉀，氫氧化鉀市場價比氫氧化鈉貴一些這是，所以氫氧化鉀更穩定，表現為熔熔點沸點更高熔沸點：KOH，答氫氧化鈉：利用焰色反應。就是氫氧化鉀。

The order of metal activity is potassium, sodium and potassium. Potassium hydroxide has stronger oxidation. The market price of potassium hydroxide is more expensive than sodium hydroxide. This is why potassium hydroxide is more stable, manifested in higher melting point and boiling point. Melting boiling point: Koh, answer sodium hydroxide: use flame reaction. It's potassium hydroxide.
