为什么说氢氧化钾比氢氧化钠碱性强？这个问题涉及到溶剂的区分效应和拉平效应。下面厂家就来为您简单分析下。

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.

物质在溶液中表现出来的酸碱性不仅和它本身有关，也和溶剂的选择有关系。简单来说，能区分两个物质酸碱性强弱的叫做区分溶剂，否则就叫做拉平溶剂。

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.

氢氧化钠和氢氧化钾同时溶解在水中，都会完全电离，这就是说二者被水这个溶剂拉平了，而表现出了相同的碱性。如果采用乙醇或液氨等作为溶剂，即可区分出二者碱性的强弱。

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.

所以说氢氧化钾的碱性比氢氧化钠的碱性强，当然这是得有前提条件的，碱的碱性强弱与碱的电离程度有关。对于氢氧化钠和氢氧化钾都是完全电离的强碱来说，可以用金属活泼性来判断，即越活泼的金属，对应的氢氧化物碱性越强。

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.

从另外一个角度来讲，溶液的碱性强弱是由氢氧根离子浓度大小决定的，氢氧根离子浓度越大碱性越强。从这个角度说，摩尔浓度相同的氢氧化钠溶液与氢氧化钾溶液的碱性是相同的。

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.
