一、引言我们知道,氨的水溶液呈弱碱性。但是,氨的水溶液为什么不是强碱而是弱碱,它呈碱性的原因和机理是什么,长期以来就是无机化学教学中存在着的一个问題。对于这个问題目前还沒有得到一致的认识。在国內已出版的各种无机化学教科书中,对氨的水溶液呈弱碱性 I. Introduction We know that ammonia aqueous solution is weakly alkaline. However, why the ammonia solution is not a strong base but a weak base, what is the reason and mechanism of its alkalinity, has long been a problem in inorganic chemistry teaching. At present there is no consensus on this issue. In a variety of inorganic chemistry textbooks that have been published in China, the ammonia solution is weakly alkaline
