Simple Distillation Of Hexane-Octane
Hexane-Octane Results The mixture that was used in this simple distillation experiment was hexane and octane. During the time the first fraction of hexane-octane mixture was collected, the temperature range was discovered to be at 41.9°C -42.5 °C. The peak area of the first fraction appeared to be 95.70 at 0.710 minutes, and 4.30% at 1.38 minutes. During the second fraction, the temperature ranges was discovered to be at 43.2°C-47.8°C. The peak area of the second fraction appeared to be 100% at 1.15 minutes. The third fraction of hexane-octane was collected, but the sample was not taken for distillation due to the teacher assistant’s specific instructions. During the fourth fraction, which consisted the remainder of the solution, the temperature …show more content…
The other group’s simple distillation experiment consisted of the alkane mixture of hexane-heptane. The results of the other group’s mixture were similarly conducted in the same experimental manner, therefore the temperature and the area and time were recorded in a respective manner. The first fraction of the hexane-heptane was recorded to have the temperature ranges of 65.9°C-71.2°C. The peak area of the first fraction appeared to be 65.76% at ———, and 34.24% at ———-. During the second fraction, the temperate ranges was recorded to be 76.4°C-80.2°C. The peak area of the second fraction were 58.77% at ——— and 39.86% at ———-. The third fraction of hexane-heptane was collected, but the sample was not taken for distillation due to the teacher assistant’s specific instructions. The fourth fraction of the hexane-heptane mixture temperature ranges were not available. The peak of the fourth fraction appeared to be 24.29% at ——- and 75.71% at ——-. All three fractions of the hexane-octane mixture that were taken during the experiment were evaluated by a gas chromatogram. The other group’s first graph showed two peaks which consisted of hexane and heptane. The hexane was more dominant in the first graph. However, the second and third graphs showed that hexane’s peak area decreased over time while the area of heptane increased over time. This was due to heptane having a higher boiling point than hexane. Therefore, a larger amount of heptane was distilled and passed through the vessel in the gas

As a whole, the experiment was conducted by four people, however, for Part A, the group was split in two to prepare the two different solutions. Calibrations curves were created for the standard solutions of both Red 40 and Blue 1. Each solution was treated with a serial 2-fold dilution to gain different concentrations of each solution.

907 Words | 4 PagesThe Octane rating refers to the amount of compression that the fuel can undergo before a combustion reaction occurs. Furthermore, the reason behind the use of isooctane instead of normal octane, is that the activation energy required for combustion is higher with isooctane due the more stable shape, translating to

Bromohexane Lab Report
1111 Words | 5 PagesThe goal of the experiment is to synthesize a bromohexane compound from 1-hexene and HBr(aq) under reflux conditions and use the silver nitrate and sodium iodide tests to determine if the product is a primary or secondary hydrocarbon. The heterogeneous reaction mixture contains 1-hexene, 48% HBr(aq), and tetrabutylammonium bromide and was heated to under reflux conditions. Heating under reflux means that the reaction mixture is heated at its boiling point so that the reaction can proceed at a faster rate. The attached reflux condenser allows volatile substances to return to the reaction flask so that no material is lost. Since alkenes are immiscible with concentrated HBr, tetrabutylammonium bromide is used as a phase-transfer catalyst.

In this experiment, dehydration and dehydrobromination undergo the elimination reaction, which includes E1 and E2 reaction. E1 is unimolecular elimination, which is removing H-X substituent to form a double bonds. The mechanism of E1 reaction includes 2 steps, formation of carbocation and deprotonation. E2 is bimolecular elimination, which is the removal of two substituent groups to form an alkene.

How Fast Does Alka Seltzer Make Gas
621 Words | 3 PagesThe control in the experiment is water. Units used while timing the productivity of gas from an Alka-Seltzer tablet in different temperatures is, seconds. In order to find out if temperature controls the rate of chemical reaction, whether hot water is a more effective way to make the gas produce at a faster speed, it would be necessary to compare the results of different temperatures at the end of each trial. In order to do this the scientists will measure the volume of gas that is produced within a 10 second interval time after the tablet begins to react.
How Do Alkaseltzer Tablets Affect The Boiling Point Of Water
527 Words | 3 PagesThe Effect of Alkaseltzer Tablets on the Boiling Point of Water Zackary Zambrano Chemistry Honors Mrs.Gregor Period-3 10/5/16 Introduction Statement of Purpose: The purpose of this experiment is to see whether or not alkaseltzer tablets have an effect on the boiling point of 100 mL of water. The control is just water, the variable groups are 100 mL of water with one tablet, and 100 mL of water with two tablets. “What exactly is boiling? The technical definition is what occurs when the vapor pressure of a liquid is greater than or equal to the atmospheric pressure. ”(Lopez,k) Simply put water, boils when enough energy is released to cause bubbles and then turn to vapor.

Gas Chromatography Lab Report
1545 Words | 7 PagesINTRODUCTION A gas chromatograph (GC) can be utilized to analyze the contents of a sample quantitatively or in certain circumstances also qualitatively. In the case of preparative chromatography, a pure compound can be extracted from a mixture. The principle of gas chromatography can be explained as following: A micro syringe is used to inject a known volume of vaporous or liquid analyte into the head or entrance of a column whereby a stream of an inert gas acts a carrier (mobile phase). The column acts as a separator of individual or chemically similar components.

How Does Acid Rain Affect Plant Growth
1186 Words | 5 PagesIntroduction: In this task I will be researching the effect that acid rain has on the rate of plant growth. Acid rain is any type of precipitation with a high pH, with high levels of nitric acids. The reason why I had chosen this topic was because acid rain seems to have a great effect on the effect of plant growth, and plants play a very important role in our ecosystem. Acid rain is a major problem in our environment when we are not able to neutralize the acidity.

967 Words | 4 PagesDETERMINATION OF PERCENTAGE ETHANOL IN BEVERAGES 1. Introduction to Gas Chromatography Gas chromatography is a very powerful separation technique for compounds that are reasonably volatile. The components of a sample partitions into two phases, the 1st of these phases is a immobile bed with a great surface area, and the other is a gas phase that permeates through the immobile bed. The sample is evaporated and passed by the mobile gas phase or the carrier gas through the column. Samples separates into the stationary liquid phase, based on their solubilities at the given temperature.
