Question
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. Drag the appropriate items to their respective bins.
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.
