A student wants to find out the cell potential of a voltaic cell made up of a nickel electrode and an iron electrode. The nickel electrode is in a 0.1 M nickel (II) sulfate solution, and the iron electrode is in a 0.1 M iron (II) sulfate solution. What is the cell potential of this voltaic cell at standard conditions (25°C and 1 atm of pressure) given the standard reduction potentials for Ni2+/Ni and Fe2+/Fe are -0.25 V and -0.44 V, respectively?
