PLEASE ONLY ATTEMPT IF YOU KNOW 100% .ALSO, BE ABLE TO PROVIDE AN EXPLAINATION. THANK YOU!

A voltaic cell is constructed in which the anode is a Cd|Cd2+ half cell and the cathode is a Fe2+Fe3+ half cell. The half-cell compartments are connected by a salt bridge. (Use the lowest possible coefficients. Use the pull-down boxes to specify states such as (aq) or (s). If a box is not needed, leave it blank.) The anode reaction is: The cathode reaction is: The net cell reaction is: the Cajcd* electrodethe Fe2Fe3+ electrode.

Explanation / Answer

The anode reaction

Cd(s) -------------------> Cd^2+ (aq) + 2e^-

The cathode reaction

2Fe^3+ (aq) + 2e^- --------------> 2Fe^2+ (aq)

overall net reaction

Cd(s) -------------------> Cd^2+ (aq) + 2e^-

2Fe^3+ (aq) + 2e^- --------------> 2Fe^2+ (aq)

---------------------------------------------------------------------

Cd(s) + 2Fe^3+ (aq) --------------> Cd^2+ (aq) + 2Fe^2+ (aq) overall net cell reaction

in the external circute electrons migrate from Cd/Cd^2+ electrode to the Fe^2+ /Fe^3+

in the salt bridege anions migrate to Fe^2+ /Fe^3+ comparment from the Cd/Cd^2+ comparment
