“守恒法”解题是指在解题的过程中利用化学反应或化学现象中的一些守恒关系来解决实际问题的一种解题方法。1995年高考试卷中,有总计52分的计算题(约占总分值150分的1/3),其中约有29分的试题可用此法很方便地解出。“守恒法”解题有解题思路简单,快速准确之功效。 在此,我将我的一些看法提出来,权作抛砖引玉之举,供大家参考、斧正。 一、“守恒法”解题之原理
The “conservation method” is a problem-solving method that solves practical problems by using some conservation relations in chemical reactions or chemical phenomena in solving problems. In 1995, there were a total of 52 calculation questions (about 1/3 of the total score of 150 points) in the examination papers, of which about 29 questions can be easily solved by this method. The “conservation method” solution has a simple, quick and accurate effect. Here, I will put forward some of my views, the right to initiate a move, for your reference, ax. I.
