Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given the reaction Fe²⁺ + MnO₄⁻ → Fe³⁺ + Mn²⁺ in an acidic solution, write the balanced half-reactions.

💡 Hint: Balance elements, then charge by adding electrons.

Challenge 2 Hard

You have the reaction Cu + AgNO₃ → Cu(NO₃)₂ + Ag. Identify oxidation and reduction, then write half-reactions.

💡 Hint: What happens to the oxidation states of Cu and Ag?
