Brφnsted的理论是现代最重要的酸碱理论,黄先生文中关于这个理论的叙述似嫌过于简略,故为补充如下:1.根据 Br(?)nsted 的主张,凡是能放出 H~+的东西,无论其是否分子,全是酸;凡是能接受H~+的东西全是碱。用一个公式来表示,便是酸=H~++碱H~+是一个极小的质点,其半径只有10~(-13)cm左右,而其电荷却有4.8×10~(-10)esu,故此 H~+的势能太大,不能独立的存在。例如溶 HCl 于水中,立即有下反应发生: The theory Brønsted is the most important theory of acid-base in modern times. The description about this theory in Huang’s text is too brief, so it is added as follows: 1) According to Br (?) Nsted’s proposition, whatever can release H ~ +, Whether it is a molecule or not, it’s all sour; anything that accepts H ~ + is all alkali. By a formula, it is acid = H ~ + + alkali H ~ + is a very small particles, the radius of only 10 ~ (-13) cm or so, while the charge is 4.8 × 10 ~ (-10) esu, so H ~ + potential is too large, can not exist independently. For example, dissolution of HCl in water, immediately under the reaction:
