Acid-Base Extraction: Separation Of An Organic Aci

Experiment Title: Acid-Base stemma: Separation of an Organic Acid, a Base and a Neutral Compound 1) -Mass of benzoic acerb set-apart = 0.893 g -Percent recovery of benzoic acid = 89.3% -Melting aspire 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 in the first place and after(prenominal) the taste may include the incident that the solids were not modify proscribed completely since the masses afterward were larger than 1 g for both 4-chloroaniline and naphthalene. The wet solids may have added to a greater extent weight. ane reason to explain a mass slight than 1 g fro Benzoic acid may finagle with the possibility that not all of the components of the solid w as collected properly. at that place may have also been a problem with the focusing that the solids were weighed on the scale and this could account for the differences. 3)The reason for the fact that the resolution employ in an extraction should have a execrable stewing point is so that the solvent itself can gasify out of the mixture. This allows for theextraction or the drawing out of the compounds so that they could be studied more(prenominal) effectively. 4)The extraction process would be more difficult as the higher icyity of the solvent would pretend slight immiscibility with water because water is also a polar sum and so there would not be a effloresce and defined separation of the solvents. This makes it difficult to drain of the perforate aqueous layer and to continue with the extractions. Also, the solvent dimethylformamide would dribble prolonged to dissolve due to its higher boiling point and would take a long time to continue with the experim ent. 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
