Seperation of Mixtures Lab

Separation of a Mixture of Solids I.Purpose: To learn how to recount a diversity of different solids, and using certain research science lab techniques. Such as, the burner, filtration system, etc. II.Procedure: Weigh unwrap the mixture, and accordingly implement different techniques to fail them from each other. Using the attractive pull back to die out iron filings, boiling the substance to separate out the rachis, and filtration paper to separate the coarseness and benzoic unpleasant. erstwhile substances are isolated and dried, weigh them out to receive a total amount. III.Experimental Data: The original weight of the mixture earlier separation was 4.6g. After separation the weights were as follows Gramspct of mixture straighten out Filings1.4g33% Sand1.2g28% T adapted flavor0.8g18% Benzoic acetous0.9g21% TOTAL4.3g one C% IV.Observations: The easiest bring out of this experiment was separating out the iron filings. With the magnet t hey confused out pretty easily. When almost boiling the sand, salt, and benzoic acid it didnt showm like it was working. I could still see remnants of the benzoic acid floating in the beaker. It seemed like they separated fine, but they never fully dissolved.

Then when doing the filtration paper it was in any chance hard because the crystals from the Benzoic acid were already forming making it hard to convey everything out of the cup. It took quite a while for the add-in salt to dry fully. V.Conclusions: It seemed that the experiment worked properly, and the substances were successfully separated. By the ch eck of the help 0.3g of materials were lost! somewhere. If I had to make an educated crack I would say that I had noticed some sand stuck to the aspect of the beaker, basically cooked on. Also, I doubt I was able to reanimate all the crystals from the cup when doing the filtration system. Those would be my reasons for error. VI.Questions: a.The flow chart I thought of at the beginning was pretty quasi(prenominal) to that of the one in reality used. I just didnt dwell how...If you want to get a full essay, order it on our website: OrderCustomPaper.com
