Ali Youssef CHM 111-0A7L Mitra Jahangeri Paper Chromatography Lab Discussion The results of the Paper Chromatography process seem to have aligned with what was expected. When the capillary action on the paper had completed and the chromatograph was finished, the distance that each cation moved (D), as well as the distance that the solvent moved (L), could be properly measured. The distance that the solvent moved ended up being 7.05cm, a number that would represent the constant variable L in…

TEE JIN FENG 15SPE072X 27012016 EXPERIMENT 7: Cannizzaro reaction and reaction of benzaldehyde with ethylene glycol Introduction: From the first experiment, the reaction of benzaldehyde and potassium hydroxide will produce two products which are benzyl alcohol and benzoic acid. We are going to look at how to get this two products separated by using their different chemical properties. For the second experiment, benzaldehyde ethylene acetal is formed when the reaction done under acidic…

Chapter 3 Process description and modeling 3.1 Process Description of Propylene Glycol Production Process The physical properties of propylene glycol are colourless and clear syrupy liquid when exists at room temperature. Besides than in liquid form, it also may exists in vapor form in air. In order to produce a colourless and odourless chemical, propylene glycol (C3H8O2, PG) involve in the reaction of propylene oxide and water. This involve the process of the hydrolysis of propylene oxide…

capacity, mixed with 20ml. of carbon tetrachloride, 30ml of glacial acetic acid and finally 1ml. of saturated potassium iodide solution. After well shaken for 1minute, 100ml. of distilled water was added to and thus free iodine liberated in the solution was titrated by 0.01N thiosulphate solution. 1 ml. of this. thiosulphate…

In this lab there was 2 objectives which where to recognize when a chemical reaction has occurred and practice collecting detailed observations in the laboratory using proper scientific terms. Reaction set #1 (1a) place approximately 1 ml of 0.1 M Pb (No3)2 solution into a test tube. Then sequentially add drops of 0.25M k2CRO4 solution until you see evidence of a chemical reaction. The products of this reaction are aqueous KNO3 and solid PbCrO4. (1b) place approximately I ml of .1M Pb (NO3)2…

The experiment that I am doing is to see if the water temperature affects the reaction time of an Alka-Seltzer explosion. I believe that it will affect the time of how fast the CO2 builds up because the faster it builds up, the quicker the reaction and therefore the explosion comes faster. Alka-Seltzer is a drug that is used for heartburn and indigestion relief, along with many other things. When Alka-Seltzer was first introduced, it was advertised in comics in the newspaper in 1931. In 2006,…

Abstract: The Grignard reaction was successfully accomplished. An amount of 1.20 ml of 2-methyl-2-pentanol was collected, and 9.60% yield was calculated based on the theoretical yield. Despite the low amount of 2-methyl-2-pentanol, its identity was confirmed by comparing the experimental refractive index and infrared spectrum to the literature refractive index and infrared spectrum of 2-methyl-2-pentanol. Statement and purpose The purpose of this experiment is to synthesize a specific alcohol…

Acid-base chemistry can be used to separate the components of a mixture, if one or more of those components are acidic or basic, based on the solubility of that mixture. Solubility is the ability of a solute to dissolve in a solvent and it’ll usually form a solution. An extraction is when compounds are dissolved from a solid into a solvent or from a solution into another solvent. Solvent-solvent is when nonaqueous solvents and reagents are used to remove an element from an aqueous solution. The…
