Challenge Problems
Push your limits with advanced challenges
You are given a reaction where Ag⁺ + Fe → Ag + Fe²⁺. Write its half-reactions and identify the oxidizing and reducing agents.
💡 Hint: Look at which species loses and gains electrons.
Balance the equation: Cr₂O₇²⁻ + H₂ → Cr³⁺ + H₂O. Show half-reactions as part of your solution.
💡 Hint: Focus on balancing charges and mass separately for oxidation and reduction.
