从近五年的江苏高考化学试卷比较分析,我们可以发现每年江苏高考化学试卷客观题的最后两道题都是溶液中粒子浓度比较及化学平衡的相关试题,这也就是我们常说的压轴题.本文就以2014年江苏高考化学试卷的第14题比较溶液中粒予浓度为例谈谈用守恒法解决溶液中粒子浓度比较问题.一、溶液中的粒子守恒电解质在溶液中的行为包括两个方面:一是电解质
From the comparison and analysis of the Jiangsu college entrance examination chemistry papers in the past five years, we can find that the last two questions of the objective questions of the annual Jiangsu Provincial College Entrance Examination chemistry paper are the particle concentration comparison and the chemical balance of the solution, which is also what we often call the finale title. This article will use the 2014 Jiangsu Provincial College Entrance Exam chemistry question 14 to compare the concentration of solution in solution to give an example to talk about using the conservation method to solve the problem of particle concentration in the solution. First, the solution of particles in the solution of the behavior of the electrolyte in the solution includes two Aspects: First, the electrolyte
