电解质溶液中微粒浓度大小比较题由于这种题型考查的知识点多,灵活性、综合性强,有较好的区分度,是当下高考的热点之一,高考试题出现率几乎100%。如何找准电解质溶液所发生的过程,理清每个过程的主次关系,把握三大守恒,是破解这类题的关键。基于这点,常见的有不等式关系的正误判断和等式关系的正误判断两个考查类型。一、找准所有过程,弄清主次关系——破解不等式关系1.找准所有过程电解质溶液的组成确定是找准所有过程的关键。首先确定溶液组成(成分以及各成分量的比
Electrolyte solution in the concentration of particles compared to the size of the questions due to this type of knowledge to examine more points, flexibility, comprehensive strong, there is a better degree of distinction is one of the hot spots for the college entrance examination, college entrance examination questions appear almost 100%. How to identify the process of electrolyte solution, to clarify the primary and secondary relationship between each process, to grasp the three major conservation, is the key to solving these problems. Based on this, it is common to judge the positive and the negative of inequalities and the positive and the negative of the equation. First, identify all the processes, to understand the relationship between primary and secondary - to solve the inequality relationship 1. Identify all the process Electrolyte solution is to determine the composition of the key to find out all the processes. First determine the solution composition (composition and the ratio of the amount of each component
