Question

A common shorthand way to represent a voltaic cell is to list its components as follows:
anode|anode solution||cathode solution|cathode
A double vertical line represents a salt bridge or a porous barrier. A single vertical line represents a change in phase, such as from solid to solution.

A. What is the anode half reaction represented by Fe??Fe2+????Ag+??Ag.

B. What is the cathode half reaction represended by Fe??Fe2+????Ag+??Ag.

C. What is the overall cell reaction?

D. What is the anode half reaction represented by Zn??Zn2+????H+??H2.

E. What is the cathode half reaction represended by Zn??Zn2+????H+??H2.

F. What is the overall cell reaction?

G. Using the notation just described, represent a cell based on the following reaction:

ClO?3(aq)+3Cu(s)+6H+(aq)?Cl?(aq)+3Cu2+(aq)+3H2O(l)
Pt is used as an inert electrode in contact with the ClO-3 and Cl?.

Enter your answer as a string. For example, Fe(ClO4)3 would be entered asFe(ClO4)3.

Explanation / Answer

a) anodic reaction :
Fe(s) ---> Fe2+(aq) + 2e-
cathodic reaction:
Ag+(aq) + e- ---> Ag(s)
overall reaction:
Fe(s) + 2Ag+(aq) ---> Fe2+(aq) + 2Ag(s)

b)
anodic reaction:
Zn(s) ---> Zn2+(aq) + 2e-
cathodic reaction:
2H+(aq) + 2e- ---> H2(g)
overall reaction:
Zn(s) + 2H+(aq) ---> Zn2+(aq) + H2(g)
