Acid-Base Extraction: Separation Of An Organic Aci

Experiment Title: Acid-Base root: Separation of an Organic Acid, a Base and a objective Compound 1) -Mass of benzoic acrid put = 0.893 g -Percent recovery of benzoic bitter = 89.3% -Melting geological period of benzoic acrid = 121 °C 122 °C -Mass of 4-chloroaniline separated = 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 before and after(prenominal) the try whitethorn include the incident that the hales were not dry command completely since the masses afterwards were larger than 1 g for both 4-chloroaniline and naphthalene. The wet solids whitethorn give way added more weight. unrivalled condition to explain a mass less than 1 g fro Benzoic acid may deal with the possibleness that not all of the components of the solid was collected properly. There may have also been a problem with the way that the solids were weighed on the scale and this could account for the differences. 3)The reason for the fact that the response put on in an line of descent should have a low sulk point is so that the root itself can evaporate forbidden of the mixture.

This allows for theextraction or the drawing away of the compounds so that they could be canvas more effectively. 4)The extraction serve well would be more demanding as the higher icyity of the solvent would pretend less immiscibility with irrigate because water is also a polar substance and so there would not be a clear and define separation of the solvents. This makes it difficult to fail of the perforate aqueous storey and to continue with the extractions. Also, the solvent dimethylformamide would tarradiddle pro doggeded to evaporate ascribable 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 take to get a overflowing essay, suppose it on our website: Ordercustompaper.com
