摘　　要：对比国内现用3种版本高中化学教材中关于学生必做实验——"一定物质的量浓度溶液配制"的编写,提出对该实验应予关注的3个问题;同时,结合相关中国和美国化学教材、文献和习题,论证了容量瓶配制溶液的精度和可用于配制溶液的范围,最后提出该实验的必需步骤。This paper showed the differences of the experiment ＂preparing a certain amount - of - substance concentration of a solution＂ in three currently-used versions of chemistry textbooks for senior high school in China, and raised three problems which should be concerned. Referring to relative American and Chinese chemistry textbooks, research papers and exercises, it showed the accuracy of the solution prepared by volumetric flask and what kind of solution could be prepared. At last, this paper proposed the necessary steps.

关 键 词：物质的量浓度 溶液配制 必需步骤
