In this study, second-year chemistry students’ understanding of essential concepts related to precipitation titration was investigated by using Vee-diagrams which are completed during the analytical laboratory course. Three Vee-diagrams concerning three argentometric titration methods were constructed prior to the laboratory study by taking into laboratory manual by the researchers. Vee- diagrams delivered to the students after completing each experiment one by one in the laboratory. Sixteen analytic chemistry students from two faculties participated in the study. It was found that the students were insufficient to define some concepts such as argentometry, precipitation, back titration and indicator. It was also concluded that the students had the calculation difficulties, especially for the back titration.
