A sample of this reaction mixture (100 μL) was added to dichloromethane (0.5 mL). Potassium carbonate (5 mL, 5 mmol) was added to the rest of the reaction mixture which was then placed in the sonication bath. A sample of the dichloromethane layer (100 μL) was extracted out every 8 minutes and added to dichloromethane (0.5 mL) until the 32nd minute. All the samples, along with benzaldehyde and ethyl cinnamate solutions were analysed by TLC with the eluent prepared from hexane (8 mL) and…

Security: When using SaaS, the client transfer sensitive information to the application over the network. Hence, it is essential to secure the connection and provide proper network security. Currently, a majority of the SaaS vendor using Secure Socket Layer…

Slime is made by mixing together borax, glue, and water. Depending on the amount of borax added to the mixture will determine the density of the slime. For our experiment in class the independent variable was the borax. The dependent variable was slime. The control group was glue. It was important to keep the amount of glue, borax, and water constant throughout the experiment. In an experiment conducted in class it was hypothesized that the more borax added the denser the slime will be.…

Identification of Analgesic Drugs by Thin-Layer Chromatography 1 (a) In thin-layer chromatography alumina or silica is used as the adsorbent material. (b) The filter paper is placed inside the beaker during separation to act as an adsorbent medium. (c) The ultraviolet lamp is used after TLC separation to illuminate the TLC sheet. (d) Aspirin, acetaminophen, and caffeine are components of analgesic drugs examined in this experiment. 2 A 6cm by 10cm pre-coated TLC sheet will be obtained. On the…

Design Analysis A connection is recognized in the optical layer regulates to carry the information among the clients in the network. The optical connection is preserved between a source node, s and destination node, d is known as an light path. The problem in finding a route for a light path with wavelength assigned to the light path is submitted as the routing and wavelength assignment problem (RWA). The problem of RWA is divided into two parts : Routing and Wavelength Assignment. In the…

Every substance reacts with force. Whether it breaks, splashes, or holds together. The science behind this experiment is the suspension. The suspension is the mixture of two substances. Where one is finely divided and dispersed in the other(SteveSpanglerScience,2015). The purpose of this experiment is to analyze the different states of viscosity, varying on the force applies to the solution. This mixture has two different states when force is being applied. When touched slowly, it is simple to…

The role of paper chromatography is to separate various and different chemicals/mixtures to show individual components within. If there are any individual components within the mixture, then they will move up the paper at different speeds and this will make the components separate. When carrying out the process, drawing an origin line near the bottom of one of the ends on the chromatography paper will be the starting point of the mixtures that you are trying to separate when they move up the…

Task 3 P1 When using thin layer chromatography (TLC) to test for purity of aspirin it is a quick and simple method. Firstly when using the TLC method you need to have a TLC sheet and mark on the sheet 0.5cm up on the sheet and draw a line, make sure you don’t press too hard on the paper as this will disrupt the absorbent on the paper. You need to make sure the samples have been marked on the paper so you don’t get mixed up and leave a gap between the aspirin samples so they don’t run together…

Thin Layer chromatography was also use to separate the mixture of fluorene and fluorenone. Thin layer chromatography is a useful separation method when the components of a mixture are in question. Analyzing what the mixture consist of can be efficiently determine by TLC by calculating Rf and comparing these values. For the separation and isolation of a mixtures components, this method is extensive and not as efficient at column chromatography. This conclusion is represented in the data gathered.…

ABSTRACT: In this experiment, we determined the relative polarity of substances using the principles of chromatography. Three substances were tested using a thin layer chromatography. The column chromatography tested a mixture of two substance which were separated as a result of the chromatography. The results for both the thin layer and column chromatography supported the hypothesis. Therefore, chromatography is an effective tool that can be used to determine relative polarities. INTRODUCTION:…
