Since standard reduction potentials range from about –3 to 3, there are just a few candidates for the reactants in a high-voltage aqueous cell (e_cell > 5 v). group 1 metals (li, na, k, rb, and cs) all have high oxidation potentials (e_ox = 2.7-3.0 v). of the species with a high reduction potential (> 2), ozone (e_red ≈ 2.1) and fluorine (e_red ≈ 2.9) are the two most common. given these common substances, can you make a high-voltage aqueous cell (e_cell > 5 v)? choose one of the following choices: yes, using either ozone or fluorine and any of the group 1 metals because e_cell = e_red + e_ox. yes, but only using fluorine and any of the group 1 metals because e_cell = e_red + e_ox. no, because group 1 metals and fluorine react with water. no, because gases cannot be oxidized in aqueous solutions.
