為什么說氫氧化鉀比氫氧化鈉堿性強？這個問題涉及到溶劑的區分效應和拉平效應。下面廠家就來為您簡單分析下。

Why is potassium hydroxide more alkaline than sodium hydroxide? This problem involves the differentiation effect and flattening effect of solvents. The following manufacturers will give you a brief analysis.

物質在溶液中表現出來的酸堿性不僅和它本身有關，也和溶劑的選擇有關系。簡單來說，能區分兩個物質酸堿性強弱的叫做區分溶劑，否則就叫做拉平溶劑。

The acidity and alkalinity of a substance in solution are not only related to itself, but also to the choice of solvent. To put it simply, the solvent that can distinguish the acidity and alkalinity of two substances is called distinguishing solvent, otherwise it is called leveling solvent.

氫氧化鈉和氫氧化鉀同時溶解在水中，都會完全電離，這就是說二者被水這個溶劑拉平了，而表現出了相同的堿性。如果采用乙醇或液氨等作為溶劑，即可區分出二者堿性的強弱。

When sodium hydroxide and potassium hydroxide are dissolved in water at the same time, they will be completely ionized, which means that they are flattened by the solvent water and show the same alkalinity. If ethanol or liquid ammonia is used as solvent, the alkalinity of the two can be distinguished.

所以說氫氧化鉀的堿性比氫氧化鈉的堿性強，當然這是得有前提條件的，堿的堿性強弱與堿的電離程度有關。對于氫氧化鈉和氫氧化鉀都是完全電離的強堿來說，可以用金屬活潑性來判斷，即越活潑的金屬，對應的氫氧化物堿性越強。

Therefore, the alkalinity of potassium hydroxide is stronger than that of sodium hydroxide. Of course, this is conditional. The alkalinity of alkali is related to the ionization degree of alkali. For sodium hydroxide and potassium hydroxide, which are both strong ionized bases, the metal activity can be used to judge, that is, the more active the metal is, the more alkaline the corresponding hydroxide is.

從另外一個角度來講，溶液的堿性強弱是由氫氧根離子濃度大小決定的，氫氧根離子濃度越大堿性越強。從這個角度說，摩爾濃度相同的氫氧化鈉溶液與氫氧化鉀溶液的堿性是相同的。

On the other hand, the alkalinity of the solution is determined by the concentration of hydroxide ions. The greater the concentration of hydroxide ions, the stronger the alkalinity. From this point of view, the alkalinity of sodium hydroxide solution with the same molar concentration is the same as that of potassium hydroxide solution.
