Redox Reactions: Balancing Equations and Oxidation States

This lecture covers the principles of redox reactions, focusing on balancing equations and determining oxidation states. Starting with the definition of oxidation and reduction, it explains how to balance redox equations in both acidic and basic mediums. The instructor discusses the concept of oxidation states and provides examples of common oxidation states for different elements. The lecture also delves into the process of assigning oxidation numbers to atoms in compounds, emphasizing rules for determining the degree of oxidation. Additionally, it explores the role of electrodes in redox reactions and the formation of electrochemical cells. The session concludes with a demonstration of a galvanic cell setup using copper and zinc electrodes.
