What is the cell potential of the concentration cell
described by:
Zn(s) │ Zn2+ (aq, 0.10 M) ║ Zn2+ (aq, 0.50 M) │ Zn(s)
Homework Answers
This is a concentration cell and the governing equation is :-
Ecell = -(0.059/n)*log[anode]/[cathode]; where n = number of electron transfer taking place = 2
Thus, Ecell = -(0.059/2)*log(0.1/0.5) = 0.021 V
