Acid-Base Extraction: Separation Of An Organic Aci

Experiment Title: Acid-Base fall: Separation of an Organic Acid, a Base and a Neutral Compound 1) -Mass of benzoic venomous set-apart = 0.893 g -Percent recovery of benzoic acid = 89.3% -Melting occlusion of benzoic acid = 121 °C 122 °C -Mass of 4-chloroaniline isolated = 1.2 g -Percent recovery of 4-chloroaniline = 120% -Melting point of 4-chloroaniline = 53°C 60 °C -Mass of naphthalene isolated = 1.36 g -Percent recovery of naphthalene = 136% -Melting point of naphthalene = 65 °C 70 °C 2)The differences in the masses of the compounds forward and after(prenominal) the taste may include the incident that the solids were not teetotal proscribed completely since the masses afterward were larger than 1 g for both 4-chloroaniline and naphthalene. The wet solids may have added much weight. ane reason to explain a mass little than 1 g fro Benzoic acid may finagle with the possibility that not all of the components of the solid was collected proper ly. in that respect may have also been a problem with the bearing that the solids were weighed on the scale and this could account for the differences. 3)The reason for the fact that the firmness of purpose employ in an extraction should have a humble stewing point is so that the solvent itself can disappear out of the mixture.

This allows for theextraction or the drawing out of the compounds so that they could be studied to a greater extent effectively. 4)The extraction process would be more difficult as the higher icyity of the solvent would pretend less(prenominal) immiscibility with water because water is also a polar perfume and so there would not be a exculpate and defined separation of the solvents. This ma! kes it difficult to drain of the perforate sedimentary layer and to continue with the extractions. Also, the solvent dimethylformamide would dribble prolonged to evaporate due to its higher boiling point and would take a long time to continue with the experiment. 5)The extraction that we did during the experiment is called Acid-Base Extraction because it...If you want to get a full essay, suppose it on our website: OrderEssay.net
