In a copper-zinc voltaic cell, one half-cell consists of a ZnZn
electrode inserted in a solution of zinc sulfate and the other
half-cell consists of a CuCu electrode inserted in a copper sulfate
solution. These two half-cells are separated by a salt bridge.
At the zinc electrode (anode), ZnZn metal undergoes oxidation by
losing two electrons and enters the solution as Zn2+Zn2+ ions. The
oxidation half-cell reaction that takes place at the anode is
Zn(s)→Zn2+(aq)+2e−Zn(s)→Zn2+(aq)+2e−
The CuCu ions undergo reduction...

1) High quality Au/Aus+ and Zn/Zn half-cells were connected with a salt bridge. Samples of water containing traces of Au(III) ions were studied using Zn(s) dipped in 1.000 M Zn²+ and Au(s) dipped in the various water samples. Standard reduction potentials from your textbook are: Aut(aq) + 3e → Au(s) +1.42 V Zn²+ (aq) + 2e → Zn(s) -0.76 V a. Determine which half-reaction is the oxidation half-reaction and which is the reduction half-reaction. b. Determine the standard cell potential...
