离子是构成许多物质的基本微粒,也是物质存在于溶液中的最常见形式·许多化合物的性质特别是在溶液中的性质,其实就是组成该化合物的各离子在溶液中表现的性质总和·学会从离子角度分析问题,常常能起到抓住本质、事半功倍的效果·一、从离子角度理解溶液中同类反应的实质同种类 Ions are the basic particles that make up many substances, and they are the most common forms of substances present in solution. The properties of many compounds, especially in solution, are actually the sum of the properties of the ions that make up the compound in solution. The ion angle analysis problem can often play a role in grasping the essence and doing more with less. I. Understanding the essence of the same kind of reaction in solution from the perspective of ions
