WebStandard cell potential is dependent on the stoichiometry of the overall reaction. A galvanic cell generates electric current spontaneously only if the cell potential is negative. Click … WebIf we are reducing copper 2+ to solid copper, the standard reduction potential is +.34 volts. If we are reducing zinc 2+ to solid zinc, the standard reduction potential turns out to be -.76 volts. The more positive value, the more likely the substance is to be reduced, so obviously +.34 is more positive than -.76.
