Review Questions

• Explain the role of electrons (e-) in redox reactions.
  • Electrons (e-) are the key players in redox (reduction-oxidation) reactions, where they are transferred from one species to another. The number of electrons gained or lost by a reactant determines its change in oxidation state, which is a fundamental property that governs the reactivity and behavior of the species in a chemical system. The transfer of electrons is the driving force behind many chemical processes, including energy production in living organisms, and tracking the flow of electrons is crucial for understanding and predicting the outcomes of redox reactions.
• Describe how the transfer of electrons (e-) is related to the concepts of oxidation and reduction.
  • The transfer of electrons (e-) is directly linked to the processes of oxidation and reduction in redox reactions. Oxidation is the loss of electrons, which increases the oxidation state of a species, while reduction is the gain of electrons, which decreases the oxidation state. The transfer of electrons from one reactant to another is what drives the redox reaction, with one species being oxidized (losing electrons) and another being reduced (gaining electrons). Understanding the flow of electrons is essential for predicting the outcomes of redox reactions and explaining the underlying chemical principles governing energy transformations and other important processes.
• Analyze how the concept of electrons (e-) is central to the understanding of redox chemistry and its applications.
