Given: What is the standard electrode potential of a galvanic ll where zinc is oxidized and copper is reduced, given their standard reduction potentials are -0.76 V and 0.34 V respectively? These values define the system as per NCERT data. Formula: Standard ll potential, E_{ll⁰ = E_{cathode⁰ - E_{anode⁰. This is standard NCERT relation. Substitution & Calculation: For Zn(s) → Zn²⁺(aq) + 2e⁻ (anode) and Cu²⁺(aq) + 2e⁻ → Cu(s) (cathode): E_{ll⁰ = 0.34 - (-0.76) = 1.10 V . Result: The computed value matches expected outcome and confirms correct choice as per NCERT.
