Title Identification of Analgesic Compounds Using Thin Layer Chromatography Abstract The objective of laboratory experiment six was to identify an unknown analgesic tablet using Thin Layer Chromatography (TLC) analysis. The procedure involved preparing TLC plates‚ solubilizing standard analgesics (ibuprofen‚ aspirin‚ acetaminophen‚ caffeine) and the unknown in isopropyl alcohol (IPA)‚ and developing the plates in acetone. Rf values were calculated for each compound. The unknown tablet showed an Rf

Esterification Lab Introduction Esterification is an important part of organic chemistry that has many practical applications. Esterification can be used to make polymers. In most cases‚ esters are used for scents – they often smell fruity and sweet. In general‚ an esterification reaction results from a condensation reaction between a carboxylic acid and an alcohol. The carboxylic acid group loses an OH group‚ and the alcohol loses and H. For instance‚ the reaction between methanoic acid and methanol

OBJECTIVE The main objective of this experiment is to carry out qualitative analysis to identify metal cations in unknown solution 1. INTRODUCTION An unknown material can be determined by using simple chemical tests and separations which is called as inorganic qualitative analysis. The separation of cations depends on the difference in their propensity to form precipitates. Separation scheme is used to classify cation into five groups on the basis of their physical and chemical behavior opposed

Date: May 22‚ 2012 Name: Cristhian Valor Organic Laboratory Pre-Lab 1. Main reaction sequence including side reaction products: 2. 3 Sentence Summary of the Experiment: The OH group on the benzene ring in salicyclic acid reacts with acetic anhydride to form an ester functional group. Thus the formation of acetylsalicyclic acid (aspirin) is referred to as an esterification reaction‚ which requires the presence of H+ (H2SO4 in our case). The technique used to purify the aspirin content

Use this packet and your book to answer the questions throughout this packet. Organic Nomenclature - Alkanes‚ Alkenes‚ Alkynes Naming organic compounds can be a challenge to any chemist at any level. Historically‚ chemists developed names for new compounds without any systematic guidelines. In this century‚ the need for standardization was recognized. For simple molecules‚ the nomenclature system worked out by the International Union of Pure and Applied Chemists (IUPAC) works well. For complex

I assessed a patient with hip problem who came to the physical therapy department in the medical complex. After the clinical examination‚ i suspect there may be a Hip Labral tear that requires further investigations and testing to confirm the clinical diagnosis. i gave the patient a written note for his physician that suggests further diagnostic testing which may help to set an accurate diagnosis of the hip problem. His doctor wrote a letter back stating that the patient should have been at first

Identification of A Mixed Culture Unknown An experiment such as this one serves the purpose of allowing us‚ the students‚ to apply what we already know about any organism and any laboratory procedure to the difficult task at hand. It is possible to identify a mixed culture by running familiar experiments on the unknown bacteria and taking information already known about specific bacteria and applying it to the results. This helps to slowly eliminate any bacteria that do not correspond with the
