A voltaic cell is constructed by immersing a strip of copper metal in 1.0 M CuSO 4 solution and a strip of aluminum in 0.50 M Al 2(SO 4) 3 solution. A wire and a salt bridge complete the circuit. The aluminum strip loses mass, and the concentration of aluminum ions in the solution increases. The copper electrode gains mass, and the concentration of copper ions decreases. What is the cell potential?
