pH Scale Explained in 2 Minutes: Acids, Bases & Real-Life Examples

Web Reference: pH的含义是氢离子浓度的负对数，用来衡量溶液的酸碱度。即pH=-lg (cH+)。 1.根据对数函数图像可知： 从表格可以看出， 温度变化的时候，理论斜率有非常明显的差异。 pH温度补偿 通常我们所说的 pH温度补偿，是将电极的斜率，补偿到当前样品测试温度下的斜率，从而在同时测得温度的情况下，pH计能够精确地测量，并自动计算得到当前测试温度下的pH值。 现在很多pH计都有自动温度补偿功能，提高 ... 14以上在水溶液里也超不了很多，理由同上。 但 非水体系 可以有高于14很多的pH值，印象中各种烷的pH值能到25～30左右，而且远远不是最高。 然后关于非水体系的pH能负多少我是真忘了，但受密度和分子量的影响应该也不会负很多。
