1. A voltaic cell is to be designed at standard state conditions using the following two half reactions: Mn+2 (aq) + 2e- ? Mn (s) Eo =
Cr+3 (aq) + 3e- ? Cr(s) Eo=
a) Using the table provided select the correct standard reduction potential for each half reaction, and write them next to each reaction.
b) Identify each half reaction as oxidation or reduction; mark which reaction occurs in anode and which in cathode.
c) Write the chemical equation describing the spontaneous cell reaction (The overall reaction):
d) Calculate Eocell .
(e) Draw a figure representing the voltaic cell, using the above reactions, label all components and indicate the direction of the electron and ion flow.
