Isolation of Component Via Extraction Objective: Separation of organic acid from a neutral compound using liquid/liquid extraction. Experimental: Similar to the “Thin Layer Chromatography” experiment, a TLC plate was ran with 2 ml of EtOAc and 8 mL of hexane in the jar. The Rf value was calculated using the formula located in the data for all the TLC plate. The mixed compound that was dotted on the TLC plate had 0.300 g of the impure benzoic acid and 10 mL of dichloromethane. A 50 mL flask…

This specifies the general interface between the network layer (IP etc.) and the Data Link layer (Ethernet, Token Ring etc.) It’s the standard for the upper Data Link layer sublayer, also known as the Logical Link Control layer. It’s responsible for flow and error control. The Data Link layer wants to send some data over the network, 802.2 LLC helps make this possible. b. 802.3 – Ethernet 802.3 is the standard which Ethernet operates by. The original 802.3 standard is 10mbps. Commonly, Ethernet…

Abstract The primary goal for this laboratory experiment was to synthesize, purify, and identify p-nitroacetanilide using acetanilide as the starting material. To test for the purity and identification of our desired product, we gathered data from: Thin Layer Chromatography (TLC), Melting Point (MP) range, Infrared (IR) spectrum, Gas Chromatography Mass Spectroscopy (GC-MS), and Proton Nuclear Magnetic Resonance (1H NMR). TLC plate indicated the formation of our pure product due to the…

Methods We began this experiment by laying out the needed materials to find the chromatography of Skittles Sweets and Sours and Crayola markers. Using a ruler and a pencil, a line was drawn on all thirty chromatography strips 1.5 centimeters from the bottom of the paper. This was to ensure that the starting point for each chromatography process was consistent. The chromatography of the skittles was found first. We began by pouring water into a cup. A pipette was used to transfer fifteen…

and the stationary phase have similarities or differences that affect the overall interaction between each other and the analyte. Separation of the individual components is achieved because each component travels at different rates. Likewise, Thin Layer Chromatography (TLC) is a chromatography technique where separation of the components in a mixture occurs on a sheet of glass,…

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…
