Section: C Lab: 2 Program: PCLT Performed: seventh November 2011 Submitted: 14th November 2011 CHEM10371 equivalence OF GRAVITY VS VACUUM FILTERATION AND AIR VS OVEN DRYING BY DETERMINING cured PRECIPITATES. BY HITENDRA CHOUDHARY PARTNER: BIMAL ADHIKARI INSTRUCTOR: ELIZABETH RIO suggest: 3 conjecture:   10 Method: 5 data: 8 Calculation: 8 Discussion: 20 Questions: 20 Conclusion: 3 References: 3 data processor: 10 Total: 100 PURPOSE:- T he economic consumption of this investigate is to compare between the solemness vs. vaccum filtering and air vs. oven dry outing method on determination of the recovery of solids from a precipitation reaction. Theory:The gravity filtration and vaccum filtration are different in the nature.Difference are following, staidness Filtration| Vac cum Filtration| 1)Gravity Filtration rely on the Gravity to capture the solvent go with with(predicate) the filter paper.2)Gravity Filtration is slow.3)Filter insoluble impurities from luscious Solution.| 1)Vaccum Filtration rely on the vaccum to let the solvent go through the filter paper.2)Vaccum Filtration is faster than Gravity Filtration.

3)Filter insoluble impurities from Cold Solution.| So here we will as well discuss the expiration between Air-drying and the Oven-drying. Air-Drying| Oven-Drying| 1)Product is dried by set inthe Air for a while2)Air-Drying product generally dont go through thermal decomposition.| 1)Product is dried by putting in the oven fo a wh ile and let it dry out.2)Oven drying can the! rmally decompose some of the product| * H20 is a lot take in a oven Filtration because it has a high possible warmheartedness of Vaporization. * Air-drying method is good if the stuff is light and casual to unthaw Ex. Ether * Oven drying is good for the stuffs ex. Polymers n ect. * There are the prefatorial type of filter papers are used in the laboratory according the retention...If you want to get a passable essay, order it on our website: OrderEssay.net
