The two solutions were combined in a microwave tube and put in the microwave for 30 minutes at 80oC. The solvent was evaporated under reduced…
Let the solution cool for a few minutes (approximately till room temperature). 5. Add the mixture to the separatory funnel. -Make sure there was no leak. 5.…
b. Add two drops of 6.0M HCl(aq), 0.5mL 10% Hydroxylamine-HCl, six drops 2.0M Sodium Acetate, and 1.0mL 0.1% 2,2-Dipyridyl solution to the test tube. c. Fill the test tube to the 10mL mark with DI water and the color will fully develop in 15 minutes d. Prepare the four other standard solutions with appropriate amounts of the solutions. 9. The sample uses 2.0mL from the volumetric flask with the dissolved Fe and add the appropriate reagents. 10.…
Lastly, to create dilution #3, 5mL of dilution #2 and 5mL of distilled water were added to the third 10mL volumetric…
Comparisons: Effect of crushed vs. whole tablet: The crushed tablet reacted faster because its surface area is smaller, allowing the particles to react faster with the water. The crushed tablet also produced frothy bubbles all over the water, whereas the reaction (bubbles) of the whole tablet was primarily around the tablet in the water. Temperature effect: The reaction was extremely slow in the cold water as molecules do not move as fast in cold water.…
Introduction: The purpose of the experiment was to determine the density of powdered grape. The company Gatorade has advertised that G2 powder replenishes fluids and electrolytes in the body’s blood stream during exercise.…
In the experiment, I tested how soapy water would affect the amount of droplets the penny can hold. The results of my experiment show that the penny holds less droplets of soap water. When the soap is added to the water, the soap collides with water breaking down the tension. As a result, it harder for the droplets to hold together. To find whether my hypothesis was right, I did several of trials to figure out whether my hypothesis was correct.…
The experiment that I will be conducting focuses on how fast one tablet of Alka seltzer can dissolve in various temperatures of water. The core of this procedure is to determine the impact that temperature has on how fast something dissolves. My hypothesis for this experiment would be that the Alka Seltzer that dissolves the fastest would be the one that was placed in the water with the highest temperature. There will be controlled and manipulated variables explained throughout the experiment. The two main things used in this experiment will be the solute and the solvent, which is Alka Seltzer and water.…
After starting with 30 mL of an unknown mixture of two solvents, fractional distillation and gas chromatography were used to identify the unknowns as acetone and toluene in a 1 to 2.04 ratio of acetone to toluene. Fractional distillation was first used to separate the unknown mixture into its components based on boiling point. Distillation refers to the method of separating components of a mixture through heating and cooling. Simple distillation, which is especially useful in the separation of less-volatile substances from volatile substances, such as sugar from water, can be used to separate a liquid-liquid mixture if the boiling points of the component liquids differ by more than 40-50°C. A plot of temperature versus volume for a simple…
Before beginning any of the tests the food samples were selected and separately blended in a small blender with water. This step was necessary for the food samples to fit into test tubes. Each food sample was left in a separate beaker to await the experiments. The first step of test 1a was to prepare 6 test tubes.…
Use a graduated cylinder to add 7.5 mL distilled H2O to the test tube. Heat the test tube while it is suspended in the hot water bath by the utility clamp on the ring stand. 4. Stir the KNO3 in the distilled H2O until all the KNO3¬ dissolves. 5.…
Experiment 3- Wear goggles and apron at all times. Put the 60 milliliters of water into the 150 milliliter beaker. Measure 1.0 grams of zinc powder on the digital balance with weighing paper. Put the zinc powder into the water and stir it with a wooden stirrer.…
Catherine Delker Honors Chemistry – Yellow Blue Beaker Experiment Lab Report 8/20/15 Blue Bottle Experiment Problem: The purpose of this lab was to determine the oxidation rate of the Methylene blue solution when tested with varying amounts of solution. Background:…
In mixture one solids “B” and “D” are present because they do not react with liquid one. Also solid “B” reacts to liquid three by changing to purple and the same reaction occurs in mixture one. Lastly, solid “D” bubbles when exposed to liquid two identical to liquid twos reaction in mixture one. The solids present in mixture two are “C” and “B” because “C” bubbles with all liquids and “B” turns purple when exposed to liquid three. The solids present in mixture three are “A” and “D” because “A” is granular as is mixture three’s texture and solid “D’s” reactions are identical to mixture three’s.…
The mixture will be heated to 45℃ and kept for 24 h. After cooling down to room temperature, the reaction mixture was directly dialyzed against DMSO, Na Cl(aq), and then DI water to remove all unreacted small organic compounds. The solution will be then frozen and…
