To solve the problem, we will follow these steps: ### Step 1: Identify the half-reactions We have two electrodes: lead (Pb) and nickel (Ni). The standard reduction potentials (E°) are given as: - For Pb: E°(Pb²⁺/Pb) = -0.13 V - For Ni: E°(Ni²⁺/Ni) = -0.25 V Since the reduction potential of Pb is higher than that of Ni, Pb will be reduced, and Ni will be oxidized. ...
