In the training program for chemistry pedagogical students at pedagogical universities, knowledge of oxidation-reduction reactions is taught when students learn about the electrochemistry chapter belonging to the theory of chemical processes. There, students are introduced to how to use standard electrode potential values of oxidation/reduction pairs to predict the likelihood of an oxidation-reduction reaction. However, a common difficulty for students is predicting reaction products of substances containing elements with several oxidation states. To simplify this problem, using the Latimer diagram will help students be more interested in predicting the stable oxidation state of the element, calculating the standard reduction potential of oxidation-reduction pairs that are not close to each other and predict the products of many complex oxidation-reduction reactions.
