Hi, I am having some issues solving for these problems. Any help would be good, thanks.
The first question is...
Is H+(aq) capable of oxidizing Cu(s) to Cu2+(aq)?
What is E°cell in this case?
I know the answer is No however I do not know how to calculate the Eo cell.
The second question...
An electrochemical (galvanic) 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 25°C if the aluminum electrode is placed in a solution in which [Al3+] = 5.4 10-3 M?
(b) When the aluminum electrode is placed in a certain solution in which [Al3+] is unknown, the measured cell potential at 25°C is 1.55 V. Calculate [Al3+] in the unknown solution. (Assume Al is oxidized.)
