An electrochemical cell, composed of an iron electrode (anode)immersed in 0.10 M Fe (NO3)2 and silver electrode (cathode)immersed in 0.11M AgNO3, was found to have a cell potential of1.21V. The standard reduction potential for Ag+ / Ag half-cell is+0.80V. The standard reduction potential for the Fe+2/ Fe half –cell is -0.45V.
1. Write the half-cell reaction at the anode.
2.Write the half –cell reaction at the Cathode
3.Write over all cellreaction
4. Determine the standard cellpotential using the standard reduction potential givenabove.
5. Determine the standard cellpotential using the Nernst equation
