### Concentration Cells and Electrochemical Potential: An Example#### Problem Statement:Consider the concentration cell below: Identify the anode, cathode, and the direction of electron flow. Calculate the cell potential at 25°C. The [Ag⁺] in the right-hand beaker is 1.0 x 10⁻⁸ M.#### Detailed Diagram Description:The diagram depicts a concentration cell consisting of two beakers connected by a salt bridge. Each beaker contains a silver electrode (denoted as Ag), immersed in solutions of different concentrations of Ag⁺ ions.- **Left Beaker:** Contains an Ag electrode and a solution with Ag⁺ concentration of 1.0 M.- **Right Beaker:** Contains an Ag electrode and a solution with Ag⁺ concentration of 1.0 x 10⁻⁸ M.#### Key Points:- **Anode and Cathode Identification:** - Anode (oxidation will occur): The electrode in the less concentrated solution (right beaker, [Ag⁺] = 1.0 x 10⁻⁸ M). - Cathode (reduction will occur): The electrode in the more concentrated solution (left beaker, [Ag⁺] = 1.0 M).- **Direction of Electron Flow:** - Electrons flow from the anode to the cathode. In this cell, electrons will flow from the right beaker to the left beaker.- **Cell Potential Calculation:** - Use the Nernst equation to calculate the potential of the concentration cell: \[ E_{\text{cell}} = E^\circ_{\text{cell}} - \frac{RT}{nF} \ln \frac{C_2}{C_1} \] - For silver electrodes, \( E^\circ_{\text{cell}} = 0 \) since the same material is in both electrodes. - Simplified Nernst equation for concentration cell: \[ E_{\text{cell}} = - \frac{RT}{nF} \ln \frac{[Ag^+]_{\text{right}}}{[Ag^+]_{\text{left}}} \] - At 25°C (298 K), \( \frac{RT}{F} \approx 0.0257 \) V: \[ E_{\text{cell
