WebAlthough hypothetical, half reactions are properly balanced chemical processes. Since V 2+ (aq) increases its oxidation number by one, from +2 to +3, in the first half reaction, an electron is shown as a product of the … Web- [Voiceover] You can use the Nernst equation to calculate cell potentials. Here we need to calculate the cell potential for a zinc-copper cell, where the concentration of zinc two plus ions and the concentration of copper two plus ions in solution is one molar, and we're at 25 degrees C. So we're talking about standard conditions here.
