Challenge Problems
Push your limits with challenges.
Question 1
Given the reaction 2MnO4− + 5Fe^2+ + 16H+ → 2Mn^2+ + 5Fe^3+ + 8H2O, identify and explain the oxidizing and reducing agents.
💡 Hint: Assign oxidation states to each species to find which undergoes oxidation and which undergoes reduction.
Question 2
