Lab Report for Extraction (Organic Chemistry)

EXTRACTION: DETERMINATION OF ITS EFFICIENCY AND CALCULATION OF THE DISTRIBUTION COEFFICIENT radical#4: Wassim Abdel Naby and Bianca Francisco Bachelor of Science degree in inter ain chemistry De La S every last(predicate)e University ABSTRACT The objective of this examine is to demonst account the concepts of extraction and to calculate the scattering coefficient. In the subprogram of extraction, sum of acetic acid was the unrivaled to be determined, and this was do through the process of titration, power employ was phenolphthalein and the titrant used was sodium hydroxide. First, 20 ml aliquot exposit helping of thin acetic acid in a cxxv mL Erlenmeyer flask titrated with sodium hydroxide. Next, the second flask containing other 20 mL of acetic acid extracted by 20 mL hazard toluene, this was done twice due to over titration in the first trial. Lastly, the ternion 20 mL aliquot portion acetic acid underwent the same procedures with flask 2 hardly this ti me with two 10 mL portions of toluene. The third part was also done twice since at first, the indicator was not added before titration. Both the second trials for flask 2 and 3 were successful enough due to the fact that it resulted into a black pink solution after titration; with all the entropy obtained, the dispersion coefficient was then calculated.

If the color is the only basis, then it must be a successful experiment, but as mentioned above, there were personal errors committed which definitely has an effect to the success rate of the experiment. asylum: This experiment aims to demonstrate liqui d-liquid extraction. Chemicals used were 18.! 0 M acetic Acid, Toluene, Phenolphthalein and 0.1M Sodium Hydroxide. In this experiment, the process of titration was used in auberge to determine the amount of acetic acid, which was done in cardinal different procedures (1 trial each). The calculations took place right after accomplishing all three separate/procedures. EXPERIMENTAL PROCEDURE: I. Preparation 2 mL acetic acid was placed...If you want to get a mount essay, monastic order it on our website: OrderCustomPaper.com
