Cobalt(II) ions (Co2*(aq)) react with 6 equivalents of a ligand (L) to from the complex cation CoL62*(aq) with Kf = 2.98 × 105. To verify this, an electrochemical concentration cell is constructed. To one half of the cell, the initial concentration of Co2*(aq) is 0.0100 M and the initial concentration of L is 1.00 M. This solution is allowed to reach thermodynamic equilibrium. A Co(s) electrode is added to this solution and it is connected with a wire to a voltmeter to the other half cell, which has a Co(s) electrode and [Co2+(aq)]=1.00M. A salt bridge connects the two half cells. Determine the Ecell (in V) immediately read when the electrodes are in their respective solution at 298 K. Note that the complex cation Col62*(aq) is a spectator species in this electrochemical concentration cell, it does not participate in a redox reaction.

![Cobalt(II) ions (Co2*(aq)) react with 6 equivalents of a ligand (L) to from the complex
cation CoL62+(aq) with K¢ = 2.98 × 105. To verify this, an electrochemical
concentration cell is constructed. To one half of the cell, the initial concentration of
Co2*(aq) is 0.0100 M and the initial concentration of L is 1.00 M. This solution is
allowed to reach thermodynamic equilibrium. A Co(s) electrode is added to this
