Abstract The goal of the soil project was to separate, purify, identify and quantify the four compounds that were present in an unknown soil sample. We were told that two of the compounds were organic and the other two were inorganic. We were given a list of all possible compounds, which we examined and used to create a procedure based on techniques we studied and practiced throughout the course that would allow us to perform both qualitative and quantitative analyses of our soil sample. We started our separation using vacuum filtration, first with ethyl acetate, and then water. This gave us a...
