离子方程式的书写是中学化学学习的重点和难点,也是高考的热点.正确书写离子方程式是学好化学的前提和保证.初学者常常感到没有规律可寻,难写、难记.那么怎样才能做到准确快捷的书写离子方程式呢?根据我多年的教学实践,谈谈笔者的体会,供同学们在学习时参考. The writing of ion equations is the focus and difficulty of middle school chemistry learning, and it is also a hot spot of the college entrance examination. Correctly writing ion equations is a prerequisite and guarantee for good chemistry. Beginners often feel that there is no law to be found, difficult to write, hard to remember. So how can we do it? How can I formulate an ion equation accurately and quickly? Based on my many years of teaching practice, talk about the author’s experience for reference when students learn.
