任教初三化学的老师都知道,《酸碱盐》部分的教学是教者感到头疼、学生感到吃力的一部分,因为这一章涉及的物质种类多、关系繁．若不理顺这一章中物质的性质与相互间的关系,学好这一章是非常困难的．怎么才能从根本上理解物质的化学性质呢?笔者认为从保持物质化学性质的粒子上着手,可达到事半功倍的效果．
The teachers teaching Chemistry have known that the teaching of the “Acid-Base Salt” section is a part of the teacher’s sense of headache and the student’s difficulty because the materials involved in this chapter are numerous and complicated. If you do not straighten out the nature of the material in this chapter and the relationship between them, it is very difficult to learn this chapter. How can we fundamentally understand the chemical nature of a substance? The author believes that starting from the particle that maintains the chemical nature of a substance can achieve a multiplier effect.
