Question

A voltaic cell is constructed in which the anode is a Fe|Fe2 half cell and the cathode is a Cd|Cd2 half cell. The half-cell compartments are connected by a salt bridge. (Use the lowest possible coefficients. Be sure to specify states such as (aq) or (s). If a box is not needed, leave it blank.) The anode reaction is:

    Answer: The Anode reaction is [tex]Fe(s)\rightarrow Fe^{2+}(aq)+2e^-[/tex]

    Explanation:

    Oxidation-reduction reaction or redox reaction is defined as the reaction in which oxidation and reduction reactions occur simultaneously.

    Oxidation reaction is defined as the reaction in which a substance looses its electrons.Oxidation occurs at anode.

    Anode : [tex]Fe(s)\rightarrow Fe^{2+}(aq)+2e^-[/tex]

    Reduction reaction is defined as the reaction in which a substance gains electrons. Reduction occurs at cathode.

    Cathode : [tex]Cd^{2+}(aq)+2e^-\rightarrow Cd(s)[/tex]
