What is the standard potential of the following cell?
Cu(s)|Cu2+(aq)||Au(s)|Au3+(aq)
Enter your answer to two decimal places in units of volts.
from data table:
Eo(Au3+/Au(s)) = 1.52 V
Eo(Cu2+/Cu(s)) = 0.337 V
As per given cell notation,
cathode is (Cu2+/Cu(s))
anode is (Au3+/Au(s))
Eocell = Eocathode - Eoanode
= (0.337) - (1.52)
= -1.183 V
Answer: -1.18 V
