高中学生,当掌握了“电离平衡”和“盐的水解”内容后,面临一个需要突破的难点,这就是如何准确地书写盐溶液中三种守恒关系,即:电荷守恒、物料(元素)守恒、(得失)质子守恒.经过长期教学探究、课后反思、学生反馈,笔者认为书写盐溶液中三种守恒关系的关键,是要将盐 After mastering the contents of “ionization balance” and “salt hydrolysis”, high school students face a difficult point to break through. This is how to accurately write the three conservation relations in salt solution, namely, conservation of charge, (Elements) conservation, (gains and losses) proton conservation.Through long-term teaching and research, after-school reflection, student feedback, I think the key to the three kinds of writing salt solution conservation is to salt
