為什么說氫氧化鉀比氫氧化鈉堿性強(qiáng)？這個(gè)問題涉及到溶劑的區(qū)分效應(yīng)和拉平效應(yīng)。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(zhì)在溶液中表現(xiàn)出來的酸堿性不僅和它本身有關(guān)，也和溶劑的選擇有關(guān)系。簡單來說，能區(qū)分兩個(gè)物質(zhì)酸堿性強(qiáng)弱的叫做區(qū)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(shí)溶解在水中，都會(huì)完全電離，這就是說二者被水這個(gè)溶劑拉平了，而表現(xiàn)出了相同的堿性。如果采用乙醇或液氨等作為溶劑，即可區(qū)分出二者堿性的強(qiáng)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(qiáng)，當(dāng)然這是得有前提條件的，堿的堿性強(qiáng)弱與堿的電離程度有關(guān)。對(duì)于氫氧化鈉和氫氧化鉀都是完全電離的強(qiáng)堿來說，可以用金屬活潑性來判斷，即越活潑的金屬，對(duì)應(yīng)的氫氧化物堿性越強(qiáng)。

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(gè)角度來講，溶液的堿性強(qiáng)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(qiáng)。從這個(gè)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.

針對(duì)這個(gè)問題，您看完以上簡單分析后有所了解了嗎？當(dāng)然您在利用氫氧化鉀工作或者做相關(guān)實(shí)驗(yàn)時(shí)要注意。更多關(guān)于產(chǎn)品的事項(xiàng)就來我們這里http://m.51fww.cn看看吧！
