Solubility test: Water (1 ml) was added too test tube, and then the unknown (2-3 drops) were also added to the test tube. A pipette was used to blow bubbles into the test tube in order to mix the solution. The solution turned cloudy white. Oil-like bubbles at the top of the solution were observed. Shift Test: In a new test tube, the Shift reagent (2 ml) was added. Then, the unknown (3-5 drops) was also added. A pipette was used to mix the solution by blowing bubbles into the test tube. The result of the Shift test was that the solution immediately urine magenta, which means altitudes are present.
Beefiest test: In another clean test tube, methanol (2-3 drops) was added. Then, the beefiest solution (1 ml) was also added, and then the unknown (5-10 drops) was added. The solution was mixed by using a pipette to blow bubbles into the test tube. Then, the solution was let sit with a cap on top. The test results were not immediately visible via a white precipitate. So, throughout the ten minute allotted beefiest test period, the solution was continually mixed with the bubbles blown through he pipette, then capped and let sit.
The result of the beefiest test was that a white precipitate formed at the top of the solution. Deform Test: In a 15 ml plastic conical vial, 1,2-demonstration (2 ml, 19. 3 mol) was added, and then the unknown (4 drops) was added. Sodium hydroxide (2 ml, 6 mol) was added. The Deform solution (3 ml) was slowly added and then diluted with water (1 0 ml). The Deform test solution was first brown from the reagent, but quickly turned yellow once mixed into the solution. Once the water was added and iced, the yellow color disappeared.
The solution was a cloudy white color. No precipitate formed during the Deform test. Synthesis reaction of a 2,4- dinitrophenylhydrazone derivative: The 2,4-dinitrophenylhydrazone solution (5 ml) was poured into a 15 ml plastic conical vial. The unknown (0. 05 g) was added. The mixed solution was observed to be an orange color. A cap was placed onto the vial. A water bath was used to warm the mixture for five to ten minutes. In the first five minutes of the test, not a lot of precipitate had formed.
So, the aped vial was tapped, and then let sit repeatedly until enough precipitate formed. Precipitate was observed forming more and more as the solution heated and time passed. The solution was let sit to cool to room temperature, and then placed into an ice bath for a couple minutes. Vacuum filtration was used to collect crystals while a lot of water was used to wash. A small piece of litmus paper was used to check the crystal’s PH. Vacuum filtration with water as a wash was utilized to wash the crystals until they turned basic. Then, the crystals were ride with filter papers.
