Consider a concentration cell similar to the one shown in
Chapter 18, Problem 66(choose chapter or problem)
Consider a concentration cell similar to the one shown in Exercise 65, except that both electrodes are made of Ni and in the left-hand compartment [Ni2] 1.0 M. Calculate the cell potential at 25C when the concentration of Ni2 in the compartment on the right has each of the following values. a. 1.0 M b. 2.0 M c. 0.10 M d. 4.0 105 M e. Calculate the potential when both solutions are 2.5 M in Ni2. For each case, also identify the cathode, anode, and the direction in which electrons flow. 67
