pH Buffer Solution

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。

YouTube Excerpt: We have four containers with universal indicator: Two of them are mixed with distilled water, the other two mixed with a buffer solution of ammonia and vinegar. We compare the pH changes when we add dropper-fulls of 1M NaOH and HCl to the dishes. We see that the water changes pH very easily, while the buffer solution is much more resistant. Always wear proper PPE when working with chemicals!
