Abstract The study is to diagnose the senior one students' knowledge of substance test in chemistry experiments and conclude the common problems. The participants come from a key high school in Zhejiang province. Ammonium ion test is the main content, including operation description, chemical terminology and mechanism understanding. Meanwhile, the differences in gender and class level are also considered, based on variance analysis. The results indicate that most of the students could not describe the experimental operation of substance test and write the corresponding chemical reaction equations, completely and accurately. What's more, they don't really understand the underlying chemistry theories. Although significant differences in gender and class level are found and the effect sizes are both limited, there are still many common problems, such as ignoring sampling and heating, confusing testing methods and misunderstanding the substance properties and chemistry mechanisms. The study provides some suggestions and implications for the teaching of chemical experiment, especially substance test.
