 P: 8 Chemistry 30 Redox tables Okay, take for instance, a standard Copper/Zinc Galvanic Cell. When you look at the Standard Potential table [which I presume is what you're wondering about], look at the value and see whether if it like to remain as the ion or the solid [which what Redox is]. The more reactive metal, will like to become the ion, and in the case of the Copper/Zinc - Zn2+ + 2e- $$\rightarrow$$ Zn (-0.76V) Cu2+ + 2e- $$\rightarrow$$ Cu(0.34V) Zinc likes to give off it's electrons to become the ion, hence the reverse voltage. So, simplified, just look at the Standard Potential if it is LOWER, so here, Zinc is being oxidized and Copper is being reduced. Hope that helped.
