The standard reduction potential values of three metallic cations, X, Y and Z are +0.52, –3.03 and – — Electrochemistry Chemistry Question

💡 Solution & Explanation

A lower (more negative) standard reduction potential indicates a higher oxidation potential, making the metal a stronger reducing agent. The order from most negative to least is Y (–3.03 V), Z (–1.18 V), X (+0.52 V). Thus, reducing power is Y > Z > X.
