微粒浓度大小的比较,是高中化学选修课本《化学反应原理》中的重点难点。学生对于水溶液中的若干离子,常常无从下手,难分仲伯。何为“母子法”?母即母亲,子即孩子,母亲个头比孩子大,智慧比孩子多,能力比孩子强,所以只要找到溶液中谁是母亲,谁是孩子,大小关系自然就比较出来了。如此形象,更易接受。水溶液中微粒浓度大小的比较,是高中化学选修课本《化学反应原理》中的重点难点。学生对于水溶液中的若干离子,常 The comparison of particle concentration is a key challenge in the “Principles of Chemical Reactions” of high school chemistry elective textbooks. Students for the number of ions in aqueous solution, often impossible to start, it is difficult to split Jones. What is the “mother and child law”? Mother is the mother, the child is the child, the mother is bigger than the child, wisdom than the child, the ability to be stronger than the child, so long as the solution to find who is the mother, who is the child, the size of the natural relationship Compare it out. This image is more acceptable. Comparison of particle concentration in aqueous solution is a key challenge in the “Principles of Chemical Reactions” of high school chemistry elective textbooks.
