Q. 6. Referring to the following table, if an electrochemical cell is composed of pure nickel and pure copper electrodes immersed in solutions of their divalent ions at room temperature (25°C) and the concentrations of Ni?+ and Cu2* ions are 0.003 M and 0.50 M, respectively, what voltage is generated at 25°C (write your calculations)? Electrode reaction Standard electrode potential (V) Au³+ + 3e → Au +1.420 Cu²+ + 2e¯ → Cu +0.340 Ni²+ + 2e¯ → Ni -0.250 Fe2+ + 2e –→ Fe -0.440 Na* +e → Na -2.924
