离子反应方程式中物质拆分的一般性与特殊性原则

The General and the Specific Principles for Separating Substance in Ionic Equations

在教学过程中,离子方程式的书写的一般拆分原则及特殊情况是教学中需要进一步突破的"瓶颈",教师应当在掌握各种电解质的一般性质的基础上,在充分了解不同物质在不同条件下的实际情况,对化学反应的实质作出准确合理的判断,这是指导好学生真正掌握书写离子方程式的关键.

The general writing principle for and exceptional case of separating substance in ionic equations is a bottleneck needing to be resolved.The author believes that the key for successful teaching of the writing of ionic equation lies in the teacher's understanding of general characteristics of electrolytes and their judgment of the essence of chemical reaction and the state of matters under different conditions.
