Separation of Mixtures Lab
A. How did your proposed procedures or flow charts at the beginning of this experiment compare to the actual procedures of this lab exercise? The procedures in the lab manual seem to follow the actual procedures of the experiment very closely with the exception that I had to use the microwave because the water with the sodium chloride had not evaporated quickly enough. B. Discuss potential advantages or disadvantages of your proposed procedure compared to the one actually used.The main disadvantage of the proposed procedure was that you had to allot long periods of time for different things to dry or evaporate making this more of a 2-3 day experiment. C.
How would you explain a sand recovery percentage that is higher than the original sand percentage? If when removing the iron particles the magnet did not attract all of the fillings this is would then affect all the other separations involved in the experiment and most likely make the final sand mass higher. D. What were potential sources of error in this experiment?Spillings, which are always likely or possible in any experiment, would make for a higher % of error in the data. Also if the magnet did not collect 100% of the iron fillings from the mixture the data would be off. Conclusions: This experiment taught me methods of how to separate different solid from a mixture. I learned that certain solids, like the sand, separate because it will not dissolve into water while the sodium chloride and benzoic acid still dissolved but even after dissolving I was able to separate the two back into a solid state after water evaporation.I encountered a few minor errors during this experiment like some spilling of the original mixture while transferring it into the weighing dish.

Also I had to eventually microwave the sodium chloride and water to finish the evaporation process. Overall I learned a lot about the separation process and enjoyed practicing the different methods even though the accuracy of my final date might be off.
