ABSTRACT
The objective of this experiment is to demonst account the concepts of extraction and to calculate the scattering coefficient. In the process of extraction, amount of acetic acid was the unrivaled to be determined, and this was done through the process of titration, power employ was phenolphthalein and the titrant used was Sodium hydroxide. First, 20 ml aliquot part helping of diluted 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 portion 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 but 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 faint 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 personal errors committed which definitely has an effect to the success rate of the experiment.


INTRODUCTION:

This experiment aims to demonstrate liquid-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 parts/procedures.

EXPERIMENTAL PROCEDURE:
I. Preparation
2 mL acetic acid was placed...If you want to get a mount essay, order it on our website: Orderessay
