Abstract 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.
