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.
