Cu half reaction

WebTo calculate the standard potential one looks up copper and zinc's half reactions and finds: Cu 2+ + 2 e − ⇌ Cu E o = +0.34 V Zn 2+ + 2 e − ⇌ Zn E o = −0.76 V. Thus the overall reaction is: Cu 2+ + Zn ⇌ Cu + Zn 2+ The standard potential for the reaction is then +0.34 V − (−0.76 V) = 1.10 V. The polarity of the cell is determined ... WebAlthough the sum of these two half-reactions gives the desired half-reaction, we cannot simply add the potentials of two reductive half-reactions to obtain the potential of a third reductive half-reaction because \(E^o\) is not a state function. However, because \(ΔG^o\) is a state function, the sum of the \(ΔG^o\) values for the individual ...
