一、牢固掌握化学实验原理任何综合性的实验包括此类习题均建立在基础实验及原理、基本操作的基础之上,对分散在各个章节独立存在的实验,在弄清实验原理的基础上,加强纵横联系、归纳对比,举一反三,融会贯通。高考化学试题中的实验题,其中一些题就是教材中的原始实验,而另一些题也可以在教材中找到其原始出处,所有试题的基本原理都源于教材的基本实验原理和基本操作。因此,加强教材演示实验和学生实验的学习就显得尤为重要。
First, a firm grasp of the principle of chemical experiments Any comprehensive experiment including such exercises are based on the basic experiments and principles, the basic operation of the foundation, scattered in various chapters exist independently of the experiment, on the basis of the experimental principle, Strengthen the vertical and horizontal links, summed up the contrast, give top priority to the situation, get through. Some of the questions in the college entrance examination chemistry questions are the original experiments in the textbooks, while others can find their original sources in the textbooks. The basic principles of all the questions stem from the basic experimental principles and basic operations of the textbooks. Therefore, to strengthen the textbook demonstration experiments and student experiments is particularly important.
