The results from this experiment provide insight on organic substances and how to use microscale science. In Part A of this experiment, the accuracy of microscale experimentation was shown through the weighing of liquids and calculating density. The calculations performed to determine the densities of the liquids were accurate. The density of water was calculated to be .94g/mL and the density of hexane was calculated to be .6g/mL. A slight deviation was shown when the results were compared to literature values. On the other hand, Part B provided insight on organic substances and their properties of solubility. Each solute was shown to be soluble in at least one of the three different solvents. Benzophenone was soluble in methyl alcohol, but not in water. …show more content…

Malonic acid was soluble in water and methanol alcohol, but not in hexane. Biphenyl was soluble in hexane, but not in water. The reason why some of these solutes are soluble in only some of these solvents is due to polarity. For Part C of this experiment, a semi-microscale procedure was used. The results from this procedure determined the purity of sulfanilamide and propose that crystallization is a successful approach to purifying an impure substance. The results from Part D of this experiment provide the conclusion that when two immiscible liquids are placed in a vial, the organic solvent is the one that sets at the bottom while the inorganic solutes remain at the top of the vial. When dichloromethane and water are compared, dichloromethane is the organic solvent. When diethyl ether and water are compared, water is the organic solvent. When two solvents are compared, the solvent with the lower density is the inorganic
