电解质溶液中三种守恒关系是中学化学电解质溶液理论部分重要知识.从近几年高考命题不难看出,这是每年必考的内容.从高考题难度分析,历年高考题以中档题、较难题为主,重点考查学生的分析能力,题型主要为选择题.学生在复习时,如何把握好溶液中的三大守恒关系,尤其是有等量关系的微粒浓度问题,常常感到无从下手或者混淆这些问题,导致做题时常常出错,若能掌握好这三种守恒关系,这类问题便迎刃而解.
Electrolyte solution of the three conservation is the middle school chemistry electrolyte solution theory part of the important knowledge from the college entrance examination proposition in recent years is not difficult to see that this is the annual exam will be content from the college entrance examination difficulty analysis, Mainly focused on examining students’ analytical skills, the main types of questions for the multiple choice questions.Presidents in the review, how to grasp the three conservation in solution, especially the relationship between the concentration of particles of the same relationship, often feel no start or confused These problems lead to mistakes often made when doing the question, if we can grasp the three conservation relations, such problems will be solved.
