7. A galvanic cell at 25°C consists of an electrode of zinc in a 0.10 M ZNSO4 solution and anther of nickel in a 0.05 M NiS04 solution. The two electrodes are separated by a porous wall and connected by an external wire. What is the emf of the cell when a switch between the two electrodes is just closed? Assume that for M→ M** +ne', the Nernst equation can be written as: e = e° + (0.059/n)×log(molar concentration of ions) e° (Zn²"/Zn) = -0.762 V and e° (Ni²*/Ni) =-0.250 V
