Question
The half-cell is a chamber in the voltaic cell where one half-cell is the site of an oxidation reaction and the other half-cell is the site of a reduction reaction. Type the half-cell reaction that takes place at the cathode for the cobalt-silver voltaic cell. Indicate physical states using the abbreviation (s), (I), or (g) for solid, liquid, or gas, respectively. Use (aq) for an aqueous solution. Do not forget to add electrons in your reaction. Part D What is the net cell reaction for the cobalt-silver voltaic cell?Explanation / Answer
D)
net cell reaction of
Cobalt silver:
Co2+ + 2 e Co(s) 0.28
Ag+ + e Ag(s) +0.7996
so
E°cell = Ered - Eox = 0.7996 - (-0.28) = 1.0796 V
