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 research laboratory techniques. Such as, the burner, filtration system, etc. II.Procedure: Weigh pop out the mixture, and accordingly employ different techniques to fail them from each other. Using the attractive motor to erupt out iron filings, boiling the substance to separate out the rachis, and filtration paper to separate the salt and benzoic unpleasant. erst substances are isolated and dried, weigh them out to receive a total amount. III.Experimental Data: The original weight of the mixture forward separation was 4.6g. After separation the weights were as follows Gramspct of mixture iron Filings1.4g33% Sand1.2g28% T adapted flavor0.8g18% Benzoic sulfurous0.9g21% TOTAL4.3g one C% IV.Observations: The easiest component of this experiment was separating out the iron filings. With the magnet they confused ou t 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 neer fully dissolved.

Then when doing the filtration paper it was in any slip hard because the crystals from the Benzoic acid were already forming making it tender to form 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 check of th e dish 0.3g of materials were lost somewher! e. If I had to make an educated crack I would say that I had noticed some sand stuck to the office of the beaker, basically cooked on. Also, I doubt I was able to obtain 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 rattling used. I just didnt dwell how...If you want to get a full essay, order it on our website: BestEssayCheap.com
