An electrochemical cell consists of a nickel metal electrode immersed in a solution with [Ni 2+ ]
Question:
An electrochemical cell consists of a nickel metal electrode immersed in a solution with [Ni2+] = 1.0 M separated by a porous disk from an aluminum metal electrode.
a. What is the potential of this cell at 25οC if the aluminum electrode is placed in a solution in which [Al3+] = 7.2 × 10-3 M?
b. When the aluminum electrode is placed in a certain solution in which [Al3+] is unknown, the measured cell potential at 25οC is 1.62 V. Calculate [Al3+] in the unknown solution. (Assume Al is oxidized.)
