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.

Electrochemical Cells
To determine the solubility product of copper(II) carbonate,
CuCO3 , a concentration cell as described on pages 71-72
of the lab handout is constructed. The temperature of the Galvanic
cell is measured to be 22.5°C, and the cell potential 282 mV (0.282
V). Using this data and Equation 8 in the lab manual, calculate the
Ksp for CuCO3 and report your answer with
three significant digits.
