This lab was very interesting and cool for many reasons! Not only did it provide a visualization of a stoichiometry problem, it also gave us a cool transformation to watch! The basics of the lab are:
1.) Record mass of starting materials (CuCl2, Fe, Jar)
2.) Mix CuCl2 and Fe in jar
3.) Leave them in the jar overnight
4.) Clean copper and nail.
5.) Wait two days for copper to dry.
6.) Mass remaining copper to perform the problem!
This lab was such great practice for calculating theoretical yield and percent yield! The reactions were cool to see too because they were so dramatic.
ReplyDeleteI agree. The labs in class help me so much by being able to see exactly what we are doing on paper except on our lab table. I guess once I make the connection, I have an easier time understanding what is going on.
ReplyDeleteI really liked this lab and thought the nail dissolving was really cool.
