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 laboratory techniques. Such as, the burner, filtration system, etc. II.Procedure: Weigh turn out the mixture, and accordingly economic consumption different techniques to fail them from each other. Using the attractive pound to ramify out iron filings, boiling the substance to separate out the rachis, and filtration paper to separate the salt 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 out front 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 acidic0.9g21% TOTAL4.3g one C% IV.Observations: The easiest part of this experiment was separating out the iron filings. With the magnet they 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 fortune hard because the crystals from the Benzoic acid were already forming making it substantial to win 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 the bear on 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 situation of the beaker, basically cooked on. Also, I doubt I was able to witness 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 truly used. I just didnt dwell how...If you want to get a full essay, order it on our website: BestEssayCheap.com
