Koh氫氧化鉀是一種無機鹽。無色晶體或白色粉末。無臭，味咸。在空氣中易潮解，可燃，遇水分解生成氫氣和氨氣。與酸類作用則放出氫氣而生成相應的堿溶液（如KOH+HCl=KClO+H2O）。

Koh potassium hydroxide is an inorganic salt. Colorless crystals or white powder. Odorless and salty in taste. It is easily deliquescent and flammable in the air, and decomposes into hydrogen and ammonia when exposed to water. Reacting with acids releases hydrogen gas and generates corresponding alkaline solutions (such as KOH+HCl=KClO+H2O).

koh氫氧化鉀的制備方法：

Preparation method of koh potassium hydroxide:

1.將碳酸鉀溶于水中，加入過量氯化鈉后加熱80°C左右脫水成氧化鉀（俗稱燒堿），經冷卻、結晶、分離得純品氫氧化鉀成品；也可用硫酸鈉與碳酸鉀反應制得。（此法有污染）

1. Dissolve potassium carbonate in water, add excess sodium chloride, heat to around 80 ° C, and dehydrate to form potassium oxide (commonly known as caustic soda). After cooling, crystallization, and separation, obtain pure potassium hydroxide product; It can also be prepared by reacting sodium sulfate with potassium carbonate. (This method has pollution)

2.由金屬鋰鹽直接電解熔融氯化鈉而制成；或用濃鹽酸處理可得到固體氫氧化鋰后再電解熔融氯化鈉即得液體氫氧化鋰成品。（此法有污染）

2. Made by direct electrolysis and melting of sodium chloride with metal lithium salts; Alternatively, solid lithium hydroxide can be obtained by treating with concentrated hydrochloric acid and then electrolyzing and melting sodium chloride to obtain liquid lithium hydroxide products. (This method has pollution)

3.由金屬鎂條置換出二氧化碳氣體中的氧原子而制成的。（此法有危險）

3. Made by replacing oxygen atoms in carbon dioxide gas with metal magnesium strips. (This method is dangerous)

4.可由碳酸鈣與水反應制得。（此法有危險）

4. It can be prepared by reacting calcium carbonate with water. (This method is dangerous)

5.可由氯酸鉀與濃鹽酸反應制取，（該反應會產生有毒的氯氣）。

5. It can be prepared by reacting potassium chlorate with concentrated hydrochloric acid, which produces toxic chlorine gas.
