Electrolytic Cells In an electrolytic cell, current is used to drive a nonspontaneous reaction. (Figure 1) In aqueous solutions, if the standard reduction potential of the metal is less than that of water, then the metal does not participate in the electrolysis, and water is reduced to hydrogen gas. If the standard oxidation potential of the anion is less than that of water, then water is oxidized to oxygen and the anion does not participate in the reaction. Figure Battery 1 of 1 Inert electrodes Part B Consider four different samples: aqueous KBr, molten KBr, aqueous KF, and molten KF. Current run through each sample produces one of the following products at the anode: liquid bromine, fluorine gas, or oxygen gas. Match each sample to its anodic product.
