- Calculate the free energy of formation of 1 mol of Cu in cells where the electrolyte is 1 mol dm-3 Cu2+ in sulfate solution, pH 0. E° for the Cu2+/Cu pair in this medium is +142 mV versus ENH.Assume the anodic reaction is oxygen evolution.Data: EH2 = -0.059 pH (V) and EO2 = 1.230 - 0.059 pH (V); 2.3RT/F = 0.059 Varrow_forwardIf the normal potential for the Fe(III)/Fe(II) pair in acid at zero pH is 524 mV Hg/Hg2Cl2 . The potential of the saturated calomel reference electrode is +246 mV versus the NHE. Calculate E0 vs NHE.arrow_forwardGiven the galvanic cell whose scheme is: (-) Zn/Zn2+ ⋮⋮ Ag+/Ag (+). If we know the normal potentials E°(Zn2+/Zn) = -0.76V and E°(Ag+/Ag) = 0.799 V. Indicate the electrodes that are the anode and the cathode and calculate the E0battery.arrow_forward
