Graph: Temperature vs. Volume for Fractional Distillation
Figure 3 This shows a direct correlation with a positive trend going upward with the temperature versus the volume. However, it should be noted that there is a drop at the 22nd ml with a discrepancy of 29 degree Celsius.
However, it is very important to see if fractional distillation is more effective or simple distillation. This is done so by plotting the data from both the experiments.
Graph: The Data for Fractional Distillation vs. the Data for Simple Distillation
Figure 4 This graph is a compare and contrast graph for both the data collected for simple distillation and fractional distillation. The orange trendline denotes simple distillation, whereas
The data was then graphed and the slope of the line of best fit for the data points was found. The slope of the line of best fit for each treatment was determined and represented
Next, about 10 mL of both solutions, Red 40 and Blue 1, were added to a small beaker. The concentration of the stock solution were recorded, 52.1 ppm for Red 40 and 16.6 ppm for Blue 1. Then, using the volumetric pipette, 5 mL of each solution was transferred into a 10 mL volumetric flask, labelled either R1 or B1. Deionized water was added into the flask using a pipette until the solution level reached a line which indicated 10 mL. A cap for the flask was inserted and the flask was invented a few times to completely mix the solution. Then, the volumetric pipette was rinsed with fresh deionized water and

Using the thermometer, the temperature was measured and recorded. Then, the 25-mL graduated cylinder was filled with 25 mL of distilled water, and its mass was measured and recorded. The density of the water was found using the temperature and the Density of water index. Moreover, the calculated volume of water was calculated using the formula of density, and the difference between observed volume and calculated volume was found. This process was then repeated using the 50-mL beaker and the results were recorded.

In order to do this we compared the two tables of carnations to daisies (table 1.1) and peonies to carnations (table 1.3).
In the second portion of this experiment we will keep the temperature constant and divide the ½ tablet of Alka- Seltzer into 2 pieces ,3 pieces and an unbroken ½ tablet. It is my belief that Alka-Seltzer
When temperature is increased, the amount of obtainable energy increases; meaning that particles will move at faster pace at a higher temperature. Thus rate at which molecules diffuse will progressively speed up as the temperature increases. However if temperature of solution is decreased the rate of osmosis will decrease and rate at which molecules diffuse will be significantly less than that of higher
The mixture was then distilled. When the temperature was reached to about 59℃, half vial of distillate (1V) and 1 mL of the liquid residue (1L) were collected. For 61.0℃, the distillation was then continued. Samples (2V, 2L) were taken at about 61.0℃.
Experiment 2: Distillation and Purification of Liquids Angela Kaiser 100125701 ELL 308 September 19th, 2015 Introduction and Experimental: The purpose of this experiment was to determine the ratio of dichloromethane (DCM) to cyclohexane in a DCM/cyclohexane solution by carrying out a fractional distillation. The temperature and volume of distillate were measured periodically to determine the volume both components in the solution. The experiment was performed as written in “Experiment 2: Distillation and Purification of Liquids” from the Chemistry 2050 Lab Manual for Organic Chemistry Part 1, Fall 2015. Results and Observations:
The fractions in the fractional distillation such as N-hexane, isohexane, methyl cyclopentane have normal boiling point close to cyclohexane which makes the recovery of cyclohexane uneconomic and difficult. 2. Quantity of cyclohexane recovered is not enough to meet the current demand since the cyclohexane content of naphtha is about 5%- 15% by weight .3 Selection of Pathway to Cyclohexane (2) Hydrogenation of Benzene: C6H6 +3H2 →
Rediet Legese iLab Week # 6 CRUDE OIL DISTILLATION Introduction: The aim of this week lab experiment is to experiment distill crude oil and to check how temperature determine the chemical properties of crude oil plus how the boiling point can also show physical properties. They are two major finding in this experiment. he first finding was the point at which the raw petroleum is heated to the point of boiling, at 275 0C, the gas and kerosene oil are refined, however the oil (lubricant ) stays as an unrefined feature oil.
We can think of each fraction as 1 unit cut into ten equal size pieces. In one unit we would shade 8 of the 10 pieces to represent 8/10 and we would shade 9 out of the 10 pieces on the other unit, because we can see that the second unit has 9 out of the 10 pieces shaded we know that 9/10 is the larger fraction. Benchmark 7/13 and 11/23 are best compared through the benchmarking strategy. We are going to use ½ as our benchmark for these two fractions. First we need to divide each of the denominators by 2 to get 6.5 and 11.5 respectively.
The thermal distillation process uses heat to evaporate water and then later liquefy again. When there is leftover heat or enough electricity available, as is often the case with factories and power plants, thermal distillation is a well-organized and workable
During the process a mixture is separated into several parts called fractions. Mixtures contain different substance with different boiling points, the differences in boiling points is the main reason fractional distillation is effective. The temperature at which a phase change occurs from liquid to vapor is the boiling point. Fractional distillation Column Fractional distillation column is a fractionating column used for separating a mixture into its various
