Lab Report for Extraction (Organic Chemistry)

EXTRACTION: DETERMINATION OF ITS EFFICIENCY AND CALCULATION OF THE DISTRIBUTION COEFFICIENT group#4: Wassim Abdel Naby and Bianca Francisco Bachelor of Science degree in chemistry De La S every last(predicate)e University ABSTRACT The objective of this prove is to demonst account the concepts of extraction and to calculate the scattering coefficient. In the handle of extraction, come in of acetic acid was the unrivaled to be determined, and this was through through the process of titration, power employ was phenolphthalein and the titrant used was atomic number 11 hydroxide. First, 20 ml aliquot get helping of thin acetic acid in a cxxv mL Erlenmeyer flask titrated with atomic number 11 hydroxide. Next, the second flask containing other 20 mL of acetic acid extracted by 20 mL pile toluene, this was done twice due to over titration in the first footrace. Lastly, the ternion 20 mL aliquot portion acetic acid underwent the same procedures with flask 2 pro vided this time 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 decease pink solution after titration; with all the entropy obtained, the distribution coefficient was then calculated.

If the color is the only basis, then it must be a successful experiment, but as mentioned above, there were ain errors committed which definitely has an effect to the success rate of the experiment. interpolation: This experiment aims to demonstrate liquid-liquid extraction. Che! micals 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 split/procedures. EXPERIMENTAL PROCEDURE: I. Preparation 2 mL acetic acid was placed...If you want to get a mount essay, set up it on our website: OrderCustomPaper.com
