Problem

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.

b. When the aluminum electrode is placed in a certain solution in which [Al  3+] is unknown, the measured cell potential at 25°C is 1.62 V. Calculate [Al 3+] in the unknown solution. (Assume Al is oxidized.)
