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 laboratory techniques. Such as, the burner, filtration system, etc.
II.Procedure: Weigh out the mixture, and accordingly use different techniques to fail them from each other. Using the attractive force to separate out iron filings, boiling the substance to separate out the rachis, and filtration paper to separate the salt and benzoic unpleasant. once substances are isolated and dried, weigh them out to receive a total amount.
III.Experimental Data:
The original weight of the mixture before separation was 4.6g.
After separation the weights were as follows
Gramspct of mixture
Iron Filings1.4g33%
Sand1.2g28%
T adapted flavor0.8g18%
Benzoic acid0.9g21%
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 case hard because the crystals from the Benzoic acid were already forming making it strong to get 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 process 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 side of the beaker, basically cooked on. Also, I doubt I was able to retrieve 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 actually used. I just didnt dwell how...If you want to get a full essay, order it on our website: Orderessay
