Experiment 12: Isopentyl Acetate 19 October 2012 Introduction: The purpose of this experiment is to prepare isopentyl acetate by direct esterification of acetic acid with isopentyl alcohol. After refluxing there is an isolation procedure where excess acetic acid and remaining isopentyl alcohol are easily removed by extraction with sodium bicarbonate and water. The ester is…

In this experiment, the azo dyes p-nitrobenzene azoresorcinol and methyl orange were prepared by the azo coupling reaction. The p-nitrobenzene azoresorcinol dye was prepared from p-nitroaniline and resorcinol. The diazonium salt formed was from the reaction of the cold solution of dissolved p-nitroaniline in hydrochloric acid and water with the solution of sodium nitrite. Azo…

Bacon, Toast, Sodium Nitrate and Potassium Bromate For Breakfast Samuel Martino Have you ever looked at the ingredients on the side of a food package? There is a lot more than the main food in the package. Usually it has real food then several different chemical compounds and preservatives listed behind the real stuff. In…

Discussion: For this week, we did the experiment under family of cereal which was about to investigate the effect of different alkaline solution on the quality of yellow wet noodles. There were four different formulations that we used. According to the table A in the procedure, it stated that for formulation 1, we were using…

Requirements: Transfer pipettes Measuring cylinders 200 ml glass beaker Hot plate Gloves Refrigerator Glass stir rod 16 oz  baking soda (Sodium Bicarbonate) 1 gallon of distilled vinegar (4% Acetic Acid) Hypothesis: Sodium acetate is the salt formed when…

uantitative Analysis of a Soluble Sulfate Steven English Lab Instructor: Dr. Campo Date: Tuesday, February 5th 2013 Pre-Lab Questions A. Adding the acid to the sodium sulfate solution results in an increase in the solubility of any free anions present in the sample. This will happen because the present anions will bind with the hydrogen…

Potassium Essay, Research Paper Potassium Potassium is a critical component in the human organic structure. Potassium had ne’er been distinguished between Na until the 18th century. Before K was recognized as an component, K carbonate was assorted with carnal fat to do soap. It was discovered by Sir Humphrey Davy in England, in 1807. Sir…

 Session 1: In this lab, we will achieve a simple Friedel-Crafts alkylation of anthracene. The choice of anthracene as an aromatic substrate stems from two considerations. First, there is a question of regioselectivity. Second, anthracene and its derivatives are highly visible under UV light. Session 2: In this lab, we will complete a partial conversion…

The chemical component K is a soft, light, silver white metal. It is a member of the alkali metals, a group ( IA of the periodic tabular array ) with similar physical and chemical belongingss. Its chemical symbol is K ( from kalium, the Latinized version of the Arabic word for “ alkali ” )…

An ester was synthesized during an organic reaction and identified by IR spectrometry and boiling point. Acetic acid was added to 4-methyl-2-pentanol. which was catalyzed by sulphuric acid. This produced the coveted ester and H2O. After the ester was isolated a percent output of 55. 1 % was calculated from the 0. 872 g of…
