1963年潘尔逊(R、G、Pearson)从大量酸碱反应和酸碱络合物稳定性等方面实验事实分析中,总结出软硬酸碱原理。规则:1、《热力学平衡状态》:硬酸优先与硬碱结合,软酸优先与软碱结合。规则:2.《化学动力学》:硬酸易于与硬碱反应,软酸易于与软碱反应。(反应速率较快)。除了特殊例外,这两条规则是和一系列化学热力学和动力学反应相对应的。值得特别提出的,这个规则并不意味着硬酸不与软碱结合,软酸不与硬碱结合。它意味着,若
In 1963, Ranson, Pearson (R, G, Pearson) from a large number of acid-base reaction and acid-base complex stability experimental analysis, summed up the soft and hard acid-base principle. Rules: 1, “thermodynamic equilibrium state”: hard acid priority and hard base combination, soft acid priority and soft base combination. Rules: 2. “Chemical Kinetics”: hard acid easily react with hard base, soft acid easy to react with soft base. (Faster reaction rate). With special exceptions, these two rules correspond to a series of chemical thermodynamic and kinetic reactions. Worthy of special mention, this rule does not imply that hard acids are not bonded with soft bases, and soft acids are not bound with hard bases. It means, if
