== 意义 ==<br />
离子方程式不仅可以表示某一个具体的化学反应，而且还可以表示同一类型的离子反应。<br />
<br />
== 正误判断 ==<br />
看离子方程式：<br />
# 是否符合客观事实；<br />
# 拆分是否正确；<br />
# 是否符合原子守恒和电荷守恒；<br />
# 是否漏写参加反应的离子；<br />
# 各微粒比与物质组成是否相符；<br />
# 是否符合题设条件。<br />
<br />
== 发生条件 ==<br />

* 肯定性原则<br />

* 互斥性原则<br />
** 在肯定某些离子存在的同时，结合离子共存规律，否定一些离子的存在；（要注意题目中的隐含条件，如酸性、碱性、指示剂的变色等）<br />
* '''电中性原则'''<br />
** 溶液呈电中性，一定有阳离子，又有阴离子。且溶液正、负电荷总数相等；<br />
* 进出性原则<br />
** 通常是在实验过程中使用，指在实验过程中反应生成的离子或引入的离子对后续实验的干扰。<br />
