Challenge Problems
Push your limits with advanced challenges
Determine the standard cell potential for a galvanic cell consisting of a silver half-cell (Ag⁺ + e⁻ → Ag) with E° = +0.80 V and a zinc half-cell (Zn²⁺ + 2e⁻ → Zn) with E° = -0.76 V.
💡 Hint: Identify which is oxidized and which is reduced.
What would happen to the cell potential if the concentration of Cu²⁺ is increased significantly in a copper-zinc galvanic cell?
💡 Hint: Recall how concentration affects the reaction quotient in the Nernst equation.
