"To raise new questions, new possibilities, to regard old problems from a new angle, requires creative imagination and marks real advance in science."

Stoichiometry Lab

Over the past few days, we have conducted a lab in which we placed an iron nail into a solution of copper(II) chloride and water. We then observed the synthesis of copper on the nail after a suprisingly short amount of time. Next, we removed all the liquid and let the copper dry out before taking the mass of it to determine whether the reaction the occurred on our nail was with Fe2+ or Fe3+. We discovered that our reaction involved Fe3+ as the theoretical yield for that was closer to our actual yield than was the theoretical yield for Fe2+.

Here are some pictures from the lab:

After about 3 hours of being submerged in the copper(II) chloride and water solution.




After 1 day of remaining in the solution.



After we drained out a majority of the liquid.
