How did your proposed procedures or flow chart at the beginning of the experiment compare with the actual procedures of this experiment? My proposed procedure was a lot more condensed and summarized as to the actual procedure which involved many steps and techniques. Though, my flow chart did produce similar results. B. Discuss potential advantages/disadvantages of your proposed procedure compared to the one actually used: The disadvantage to my proposed procedure would be that the results would not be as accurate, and probably would not have been conclusive.C. How would you described a sand recovery percentage higher than the original sand percentage? Either the sand was not completely filtered out of the solution when testing the other components, or when the sand avgas exposed to air other particles bonded to the sand which would create the appearance of an increase in percentage.

D. What were potential sources of error in this experiment? There were many potential sources Of error in this experiment, the first being that you may not have fully separated each component to its fullest extent.Mathematical ululations could also cause room for error if you miscalculated any one Of the substances tested. The initial calculation of the mixture in the beginning could have very well not been measured accurately which would change the entire results of the experiment.

Conclusion: The mixture could be separated into individual components by evaporation, filtration, magnetic separation, and distillation. Not all techniques will work on each substance, and the characteristics of each substance determine which technique to use based on the solubility of that substance.
