Expt. 8.1 Thin Layer Chromatography (TLC) Analysis of Analgesics Krista Jinks CH 211L Section F 10/27/14 I. Abstract: The objective of this experiment was to analyze analgesic tablets by TLC to determine what analgesics they contain. The analgesics that could be in the tablets included ibuprofen‚ acetaminophen‚ aspirin‚ and caffeine. Through the use of TLC‚ unknown substance #62 was found to be Bayer Aspirin because it only contained aspirin. II. Introduction: 1. Briefly describe

Separating Water Soluble and Acetone Soluble Inks through Chromatography Abstract: Chromatography is a term used to define a set of laboratory techniques for the separation of mixtures. Through Chromatography we analyzed complex mixtures. In our recent lab we analyzed complex mixtures. The purpose of this lab was to find whether the water soluble or acetone soluble liquid traveled farther. In our recent lab we measured the distance traveled by the different colored water and acetone soluble

Resolution of Matter into Pure Substances – Paper Chromatography Abstract The purpose of this laboratory was to determine how different substances have different solubilities in a given solvent. This was accomplished using the method of chromatography. The solubility of each substance was first determined by dropping a drop or two of each on a line drawn 2 inches above the bottom of a piece of paper. Then the paper was lightly bent in order to tape both sides of the paper leaving about a 4 centimeter

The premises of "Trump immigration policies disrupt health care: Column." is the constant lack of physician shortage that the United States has faced. This is not just a current problem‚ getting trained physicians to help in poor urban areas has been a problem for decades. Preisedent Trump’s new travel ban has blocked thousands of Visa holders from entering the country or causing a delay upon their arrival. Foreign doctors have helped in rural urban areas because they came to the US to recieved other

Paper chromatography is a useful technique for separating and identifying pigments and other molecules from cell extracts that contain a complex mixture of molecules. The solvent moves up the paper by capillary action‚ which occurs as a result of the attraction of solvent molecules to the paper and the attraction of solvent molecules to one another. As the solvent moves up the paper‚ it carries along any substances dissolved in it. The pigments are carried along at different rates because they

Pigs are often depicted as a character who’s unclean‚ greedy‚ and conceited; being the displeasing character in stories or in religions. Marianne DeKoven‚ who wrote the article “Guest Column: Why Animals Now?”‚ explains how anthropomorphism removes the animal’s real purpose in this world. “All literary representations of animals no more form a unified or even meaningful category than do those of women or the working class.”(363) She

5.05 Mixtures and solutions Lab report Ink Chromatography Chromatography is also used to compare and describe chemical substances. The chromatographic sequence of sorbed substances is related to their atomic and molecular structures. A change in a chemical substance produced by a chemical or biological reaction often alters the solubility and migration rate. With this knowledge‚ alterations or changes can be detected in the substance. Chromatography serves mainly as a tool for the examination and

curvature in the neck‚ upper trunk and lower trunk is normal. Humans need these spinal curves to help the upper body maintain proper balance and alignment over the pelvis. However‚ when there are abnormal side-to-side (lateral) curves in the spinal column‚ we refer to this as scoliosis. Scoliosis occurs most often during the growth spurt just before puberty. While scoliosis can be caused by conditions such as cerebral palsy and muscular dystrophy‚ the cause of most scoliosis is unknown. Scoliosis
