电解质溶液中的离子行为按照从简单到复杂,从单一物质到多种物质的认识层次,涵盖了溶剂水、弱电解质的电离平衡、盐类的水解平衡、沉淀溶解平衡、离子反应~([1])的相关知识,是高中阶段的重要内容,也是高考的常考考点之一。其中溶液中“三大守恒”更是各省市高考、模考所钟爱的考查要点,质子守恒的书写及其正误判断是学生学习的难点,也是我们教学的难点。一般书写质子守恒的方法也就是我们很多教师在
The ionic behavior in electrolyte solution follows the level of understanding from simple to complex, from single substance to multiple substances, and covers the ionization equilibrium of solvent water and weak electrolyte, the equilibrium of salt hydrolysis, the equilibrium of precipitation dissolution, the ionic reaction ~ ([1 ]) Is related to knowledge, is an important part of high school stage, but also one of the usual entrance examination entrance. Among them, the solution of “three major conservatories” in the solution is the most important examination points of entrance examinations and mode examinations of provinces and cities. The writing of proton conservation and its positive and negative judgments are the difficult points for students to study and also the difficulties of our teaching. The general method of writing proton conservation is that many of our teachers are there
