I soaked a porous cup in tap water for a few minutes and then i
let it stand in a 100 ml beaker containing 10ml of 0.1 M FeSO4. I
added enough 0.1M CuSO4 to the cup until the two liquid levels were
the same height. I inserted a zinc strip into the 0.1 M FeSO4 and a
shiny copper strip into the 0.1 M CuSO4. I connected the...

Prelab Activity:
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.
For the Galvanic cell you will construct in PART B,...
