Separation Of Mixture Of Solid Lab Essay

The purpose of this lab is to compare and contrast each fast food choice and view the results as to which will contain the most and the least fat. I think the Carl’s burger will have the thickest layer of fat because it has the most saturated fat in comparison to all the others. And I think the McDonald’s Chicken Sandwich will have the thinnest layer of fat because the amount of saturated fat is the lowest compared to the others. Introduction: Our society feeds off fat, both literally and figuratively

bimolecular nucleophillic substitution (SN2) and reactions 2 and 3, went through unimolecular nuclephillic substitution (Sn1), due to carbocation rearrangements forming 2 products each through a stepwise process. Conducting various tests through separation and purification methods can test the reactions and their hypothesized pathway, also Analyzing data through infrared spectroscopy (IR), proton nuclear magnetic resonance (1H NMR) and gas chromatography (GC) can give a final overall picture to the

During this experiment the His-tagged protein RNase H was purified using affinity chromatography. The source of over-expressed His-tagged RNase H used was 5.0 mL of E. coli lysate. The experiment was performed in partners using different materials in order to prepare the needed three buffers to an approximate pH value of 7.9. Once the three buffers were ready a minicolumn was packed with 0.5 mL of Ni-NTA agarose and then different solutions were used to wash the column, starting with DI water, followed

We made sure the solution is strongly acidic by testing it with litmus paper getting a pH of 2. We then cooled the mixture to room temperature swirling the flask occasionally in an ice bath. We collected the aspirin by vacuum filtration and washed the aspirin on the filter with cold distilled water. We let it air dry for 30-35 minutes and then weighed the aspirin. It

Chem 201 Lab October 21, 2011 Lab #6: Preparation of 2-chloro-2-methylbutane – an Sn 1 Reaction Purpose The purpose of this experiment was to prepare an alkyl halide, 2-chloro-2-methylbutane by reacting 2-methyl -2-butanol (t-amyl alcohol) with hydrochloric acid. Alkyl halides are of wide interest because they are widespread and have diverse beneficial and detrimental impacts .The overall reaction is given below: Procedure 1 ml of 2-methyl-2-butanol was measured using 1 ml syringe and

Analysis mode: The procedure is done to estimate different types of molecules and their individual quantities in the mixture using the help of a detector. 2. Preparative mode: Here the intention of process is to separate large amounts of specific molecule from a mixture. The molecule or substance eluted is of highest purity. The column size, sample size is comparatively large than that of analytical mode. Advantages of HPLC: • It includes both

to physically separate the different dyes that are used to create the variety of M&M colors while using paper chromatography. Lastly, the experiment results were satisfactory, but were not 100% accurate. Paper chromatography does indeed separate mixtures, but this method is not the most reliable technique. Introduction: What exactly is chromatography and how does it relate to

containing the mixture was placed on a hot plate for 5 minutes. Quickly after 5 minutes, the flask was removed and 2 mL of water were added, this addition was done in

which is a strong acid catalyst. The mixture of the reactants was heated for ten minutes in a hot-water bath at a temperature of sixty degrees Celsius and was given time to cool in a different beaker for five minutes. The product formed was a colorless, insoluble liquid that smelled like banana candy. Two minutes later, a reverse reaction had occurred and the aroma of banana changed to a marker smell. The pentyl ethanoate was on the surface of the water mixture while the sulfuric acid, ethanoic acid
