Setup: A magnesium electrode dipped in a magnesium sulfate solution and an iron electrode dipped into iron (III) sulfate solution
Am I right in thinking that you need to first identify the redox reactions to determine to determine overall voltage of the cell at standard conditions?
I have identified Mg to be oxidized to Mg(2+) at the anode, but I am not sure which is reduced at the cathode. Would it be the sulfate ions?
If it is indeed the sulfate ions, I have calculated the standard electrode potential to be 2.54 volts (is this correct)?
