How do you calculate theoretical voltage?
For emample, if you are dealing with Copper and Zinc, you first take the half equations Cu2+ + 2e- --> Cu +0.34 Zn2+ + 2e- ---> Zn -0.76 then, you decide which one is reduced and which one is oxidized, the one with the more positive voltage is reduced, so in this case the copper is reduced. the overall reaction changes to Zn- ---> Zn2+ + 2e +0.76 Cu2+ + 2e- --> Cu +0.34 ---- Zn + Ni2+ ---> Ni + Zn2+ + 0.5 you add the voltages and get 0.5 as an experimental voltage

What happens to glucose or galactose when the Cu2 plus in benedicts is reduced?
"All monosaccharides and most disaccharides can be oxidized. When the cyclic structure opens, the algehyde (-COOH) group is availabel for oxidation. Benedict's reagent contains Cu2+ ion that is reduced. Therefore, all the sugars that react with Benedict's reagent are called reducing sugars. When oxidation of sugar occurs, the Cu2+ is reducted to Cu+, which forms a red precipitate of cuprous oxide, CuO(s). The precipitates colors varies from green to fold to red depending on the concentration of the reducing sugar." Caralyst Pearson Custom Publishing 2011 p.65

Calculate the standard emf of a cell that uses the Mg Mg2 plus and Cu Cu2 plus half cell reactions at 25 degrees C?
Cu + Mg2 --------> Cu2 + Mg Cu --------------> Cu2 + 2e Mg2 + 2e --------> Mg Cu --------------> Cu2 + 2e (E = +0.35) Mg2 + 2e --------> Mg (E = -2.36V) +0.35 + (-2.36) = -2.01V --------------------------------------… Mg + Cu2 --------> Mg2 + Cu Mg --------------> Mg2 + 2e Cu2 + 2e --------> Cu Mg --------------> Mg2 + 2e (E = +2.36V) Cu2 + 2e --------> Mg (E = -0.35V) +2.36 + (-0.35) = +2.01V
Do Cu plus and Cu2 plus plus violate the octet rule?
