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,...

Question 3: In a lab experiment, you are tasked with determining the electrochemical reaction that can occur between aqueous hydrochloric acid (HCl)) and solid magnesium metal (Mg). When the magne- sium is placed in solution, gas bubbles begin to appear around the metal and evolve from solution. (a) Write out the two half reactions that occur when the magnesium is placed in the hydrochloric acid solution. Which species is the getting oxidized? Reduced? (b) Which species is acting as the...

The first two pages are a background of the lab and there is a
page with the results. I would appreciate any help with this. If
needed I have the pre-lab questions as well. I added in the pre-lab
questions I will get them answered and updated again if that is
what is needed.

The first two pages are the background of the lab. I would
appreciate any help with the pre-lab questions, even if you cannot
answer them all, so I could continue to the post-lab on my own.
