Redox reactions and their balancing are one of the basic chemistry subjects in which students may experience remarkable learning difficulties at the beginning of their university career. This topic represents an evolution of stoichiometry concepts related to the balancing of chemical reactions and can be taught with different approaches as a function of the in-depth analysis of the connected concepts as well as of the students' backgrounds and educational objectives. In this article, we focus our attention on the thermodynamic approach, highlighting its versatility along with its strengths and weaknesses.
