Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Calculate how much mass of aluminum would be produced during electrolysis when a current of 5.0 A flows for 2 hours in the half-equation Al³⁺ + 3e⁻ → Al.

💡 Hint: Remember to divide by the number of moles of electrons transferred for aluminum.

Challenge 2 Hard

If you have a solution where you electrolyze 2 moles of copper and collect 3.00 A for 1 hour, how many grams are collected?

💡 Hint: Ensure to track the stoichiometry correctly!
