Homework Answers
The cell representation of the given voltaic cell is
Zn|Zn²+||Cu²+|Cu
The side containing zinc is the anode compartment (oxidation half cell ) where oxidation takes place and the Zinc electrode is the anode
Oxidation half cell is Zn ----> Zn²+ + 2e-
The side containing Copper is cathode compartment (reduction half cell) where reduction takes place and Cu is the cathode
Reduction half cell is given by Cu²+ + 2e- -----> Cu
The purpose of the Na2SO4(salt bridge) is to maintain electrical nuetrality within the internal circuit.
