氢氧化钾的性质
Properties of potassium hydroxide
白色粉末或片状固体，熔点380 ℃，沸点1324 ℃，相对密度2.04 g/cm3，折射率n20/D 1.421，蒸汽压1mmHg（719 ℃）。其性质与氢氧化钠相似，具强碱性及腐蚀性，0.1 mol/L溶液的pH为13.5。极易吸收空气中水分而潮解，吸收二氧化碳而成碳酸钾。溶于约0.6份热水、0.9份冷水、3份乙醇、2.5份甘油，微溶于醚。当溶解于水、醇或用酸处理时产生大量热量。中等毒，半数致死量（大鼠，经口）1230 mg/kg。
White powder or flake solid, melting point 380 ℃, boiling point 1324 ℃, relative density 2.04 g / cm3, refractive index N20 / D 1.421, vapor pressure 1mmhg (719 ℃). Its properties are similar to that of sodium hydroxide, with strong alkalinity and corrosiveness. The pH value of 0.1 mol / L solution is 13.5. It is easy to absorb moisture in the air and deliquescence, and absorb carbon dioxide to form potassium carbonate. It is soluble in about 0.6 parts of hot water, 0.9 parts of cold water, 3 parts of ethanol, 2.5 parts of glycerol, slightly soluble in ether. When dissolved in water, alcohol or treated with acid, a lot of heat is produced. The median lethal dose (LD50) was 1230 mg / kg in rats.
氢氧化钾的溶液配制
Preparation of potassium hydroxide solution
配制500 ml 、10%的氢氧化钾溶液配制方百法：
To prepare 500 ml 10% potassium hydroxide solution
1、计度算氢氧化钾的称量质量m = 500 gx10%= 50 g ；
1. The weight of potassium hydroxide is 500 G x 10% = 50 G;
2、在100ml 小塑料问杯里在电子天平上称量50.0 g氢氧化钾；
2. Weigh 50.0 G potassium hydroxide on an electronic balance in a 100ml plastic cup;
3、用蒸馏水缓慢加答入，搅拌溶解，稀释后再转移到500 ml 容量瓶中定容；
3. Add distilled water slowly, stir and dissolve, then transfer to 500 ml volumetric flask for constant volume after dilution;

4、再回转移到500 ml的塑料试剂瓶中，贴答标签。
4. Then transfer to 500 ml plastic reagent bottle and label.
氢氧化钾首先少量的此溶液可以存放在玻璃瓶，但是不能用玻璃塞（一般是用木塞，胶塞），因为普通玻璃的组成中含有较多的二氧化硅，它们会发生反应，其中反应物硅酸钠具有粘稠性，会使塞子黏住导致开不了。储存时应保持包装容器的完整、密封性；不得与易燃物和酸类共贮混运；要注意防潮、防雨；失火时，可用水、砂土和各种灭火器扑救，但消防人员应注意水中溶入烧碱后的腐蚀性；可采用铁桶或其他密闭容器包装，包装容器应符合有关规定，桶盖应密封；
First of all, a small amount of potassium hydroxide solution can be stored in a glass bottle, but glass plug (usually wooden plug or rubber plug) can not be used. Because the composition of ordinary glass contains more silica, they will react, and the reactant sodium silicate has viscosity, which will make the plug stick and cause it to fail to open. During storage, the packaging container shall be kept intact and sealed; it shall not be stored and transported together with inflammables and acids; attention shall be paid to moisture-proof and rain proof; in case of fire, water, sand and various fire extinguishers can be used to put out the fire, but fire fighters shall pay attention to the corrosiveness of water dissolved in caustic soda; iron drums or other closed containers can be used for packaging, and the packaging containers shall comply with relevant regulations, and the barrel cover shall be sealed;
