Chapter 19, Problem 87GQ

Two Ag⁺(aq) | Ag(s) half-cells are constructed. The first has [Ag⁺] = 1.0 M, the second has [Ag⁺] = 1.0 × 10⁻⁵ M. When linked together with a salt bridge and external circuit, a cell potential is observed. (This kind of voltaic cell is referred to as a concentration cell.)

1. (a) Draw a picture of this cell, labeling all components. Indicate the cathode and the anode, and indicate in which direction electrons flow in the external circuit.
2. (b) Calculate the cell potential at 298 K.
