In this experiment the following materials were used: spatula, glass stir rod, small test tube and rack, six large test tubes, 10mL graduated cylinder, grease marker, 100 mL beaker(s), glass jar with lid, Sharpie marker, pipettes with bulb, two 2 dram vials with black lids, funnel, 50-100 mL graduated cylinder, filter paper, hotplate, 400-600mL beaker and ice, watch glass and ½ of a glass petri dish. In addition, the organic compound, benzoic acid, the inorganic compound, iron sulfate, and all chemicals in table 2 were used. Hazards associated with this experiment include glassware breaking and cutting through skin. There was the danger of burning oneself through the use of the burner. Hazards associated with chemicals are that they are…show more content…
(In this case, six mL of ethanol was added to the six test tubes). The latter two steps were repeated for compound 2. The six test tubes were then placed in a labeled jar filled with a third of diethyl ether and was put away to be checked on in a week. When checked, there was no indication of crystal formation. The only change that was present was that the jar had small black particles floating around in the diethyl ether due to sharpie remnants. The next part of the experiment was the liquid to liquid diffusion. Two vials were obtained and labeled (1 and 2). Then in a beaker, 50 mg of the first compound was dissolved with 2-5 mL of a solvent from Part A that the two compounds readily dissolved in (which in this case was ethanol). This solution was then transferred into the first vial. By referring to table three from the experiment, a new miscible solvent with a lower density (than the solvent used) was chosen to be added onto the solution in the vial. This meticulous procedure consisted of adding 2-3 pipette full amounts of the lower density solvent onto the solution in the vial with the precaution of not allowing the solvents to mix. After obtaining the layered solutions, the cap was screwed and the vial was placed in a certain area to be referred back to in week for potential crystal formation. These series of steps were repeated for the second compound. For both the benzoic acid solution and the iron sulfate solution, two pipette full
