一、教材分析(一)本节课在教材中的地位和作用人教版《化学反应原理》(选修4)第三章介绍了弱电解质的电离以及平衡移动原理等知识,第三节《盐类的水解》承接了《化学平衡》和《电离平衡》的原理,也是对这些原理的具体运用,同时还是学习《难溶电解质的溶解平衡》及《电化学》的理论基础。 First, the textbook analysis (a) the class position and role in the textbook PEP “chemical reaction principle” (elective 4) Chapter III introduces the weak electrolyte ionization and the principle of equilibrium movement and other knowledge, the third section “salt Hydrolyzate ”to undertake the“ chemical equilibrium ”and“ ionization balance ”principle, but also on the specific application of these principles, but also learn the“ insoluble balance of dissolved electrolytes ”and“ electrochemical ”theoretical basis.
