Consider four different samples: aqueous LiF, molten LiF, aqueous AgF, and molten AgF. Current run through each sample produces one of the following products at the cathode: solid lithium, solid silver, or hydrogen gas. Match each sample to its cathodic product. Drag the appropriate items to their respective bins.

Answer:

Molten LiF forms solid lithium

Aqueous AgF forms solid silver

Aqueous LiF forms hydrogen gas.

Explanation:

Aqueous solution of [tex]LiF[/tex] has water molecule, there will be competing will be two competing cations for reduction, while [tex]Li^{+}(aq)[/tex] and[tex]H^{+}(aq)[/tex].However the reduction potential of [tex]H^{+}(aq)[/tex] is  more than that of the [tex]Li^{+}(aq)[/tex] . Hence, [tex]H^{+}(aq)[/tex] reduced to hydrogen gas.

Molten[tex]LiF[/tex]  has only solid form of [tex]LiF[/tex] and [tex]Li^{+}(aq)[/tex] reduced to form [tex]Li[/tex] solid.

An aqueous form of [tex]AgF[/tex] contains water molecules.there will be competing will be two competing cations for reduction, while [tex]Ag^{3+}(aq)[/tex] and[tex]H^{+}(aq)[/tex].However the reduction potential of [tex]Ag^{3+}(aq)[/tex] is  more than that of the [tex]H^{+}(aq)[/tex] . Hence, [tex]Ag^{3+}(aq)[/tex] reduced to solid silver.

Therefore, Molten LiF forms solid lithium

Aqueous AgF forms solid silver

Aqueous LiF forms hydrogen gas.
