In a standard cell, a zinc electrode placed in a 1 molar Zn2+ solution is connected to a nickel electrode placed in a 1 molar Ni2+ solution. The 2 solutions are connected with a salt bridge. The standard reduction potential of Zn\({}^{2+}\)[Z-N two plus] is

-0.76 Volts. If the standard electromotive force of this cell is +0.48 Volts, what is the standard reduction potential of Ni\({}^{2+}\)[N-i two plus] in volts?
-0.28
