The reduction potential of being reduced to Pt is 1.20V. The reduction potential of
being reduced to Co is -.28V. This information is used to construct a galvanic cell.
What is the cell diagram of this cell?
A.

D.
A
A cell diagram traces the path of the electrons from the anode (Co)to the cathode (Pt)l The electrons begin in the solid cobalt and are released from the cobalt as it oxidizes. These electrons then travel to the where they cause the platinum to be reduced to solid platinum.
