Final answer:
A concentration cell is constructed by connecting two nearly identical half-cells, each based on the same half-reaction and using the same electrode, varying only in the concentration of one redox species. The potential of a concentration cell is determined only by the difference in concentration of the chosen redox species. In this case, the voltage of the concentration cell with silver electrodes and solutions containing silver ions of different concentrations can be calculated using the Nernst equation.
Step-by-step explanation:
A concentration cell is constructed by connecting two nearly identical half-cells, each based on the same half-reaction and using the same electrode, varying only in the concentration of one redox species. The potential of a concentration cell is determined only by the difference in concentration of the chosen redox species.
In this case, the concentration cell is constructed with silver electrodes and two half-cells containing silver ions. One half-cell has a concentration of 0.650 M Ag+ ions, and the other half-cell has a concentration of 0.700 M Ag+ ions. To calculate the voltage of the cell, we use the Nernst equation:
Ecell = E° - (0.0592/n) * log(Q)
where Ecell is the cell potential, E° is the standard cell potential, n is the number of electrons transferred in the balanced equation, and Q is the reaction quotient (the ratio of concentrations of products to reactants).
