Balancing Redox Reactions in Basic Solution | AP/IB/High School Chemistry

Balancing redox reactions is very different from balancing normal chemical equations because electrons also need to be accounted for. There are two main methods to balance redox reactions: the oxidation number method and the half-reaction method. In this video, I focus on the half-reaction method, a powerful and systematic approach. We’ll work through the example FeO + MnO₄⁻ → Fe₂O₃ + MnO₂, showing how to balance it step by step in acidic solution first, and then applying the additional step needed for basic solution. You’ll learn how to: - Recognize why electrons must be balanced in redox reactions - Split the equation into oxidation and reduction half-reactions - Balance all atoms except oxygen and hydrogen - Balance oxygen with H₂O and hydrogen with H⁺ - Balance charges by adding electrons - Combine half-reactions so electrons cancel - Add the extra step for basic conditions At the end, we’ll put everything together so you can confidently balance redox reactions in both acidic and basic conditions. This tutorial is perfect for high school and college chemistry students. 📒 *Chapters* 📒 --------------------------- 0:00 Introduction 0:20 Two Methods for Balancing Redox Reactions 0:40 How to Separate Half Reactions 2:07 Adding electrons to the Half Reactions 4:08 Adding the Two Half Reactions 5:11 Balancing shown under Acidic Condition 5:30Additional Step for Basic Solution 6:32 Final Balanced Equation under Basic Condition & Recap ---------------------------- *Stay connected!* 📞 *Twitter (X):* /ChemLessonsMona *Instagram:* /chem_lessons_with_Mona *Website:* http://mlchemistry.com/ 🔔 Subscribe for more chemistry lessons: / @chemlessonswithmona 📺 Watch the full video here: https://youtu.be/mYkbsxSWc9U 🎥 Check out the playlist for more chemistry topics: https://youtube.com/playlist?list=PLMAhauS3prQTwrA56IkW2kx__m0r8HzIy&si=1VztSPkmo5WZ2RPM --- Thank you for watching!
