We created a Cu/Zn cell by placing 0.10 M ZnSO4 in to
a porous cup and poured 0.10 M CuSO4 in to a beaker
surrounding the porous cup. We placed a Zn electrode in to the Zn
solution and a copper electrode in the Cu solution.
a) Calculate the expected potential V (our measured potential V was
around 1.09 so it should be around there I believe)

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...
