Qualitative Analysis Lab Report Organic Chemistry Laboratory II ABSTRACT: The purpose of this lab was to separate and purify two unknown compounds, one solid and one liquid, from an ethereal solution using the techniques of chemically active extraction, vacuum filtration, simple distillation, and recrystallization. Then identifying information was compiled about these unknowns by obtaining experimental melting/boiling point ranges, and analyzing IR and proton/carbon NMR spectrums It was determined
National University of Singapore CM1501 Organic Chemistry for Engineers Lab Report Experiment 2: Separation and Identification of Two Organic Compounds 10th October 2013 Abstract This experiment involves the separation and identification of 2 organic compounds (1 Neutral Compound and 1 Acidic Compound) in a mixture. Separation techniques used in this experiment include solvent extraction, simple distillation and recrystallization using a suitable solvent determined through a solubility
Abstract Recrystallization is a common method of purifying organic substances through the difference in solubility at different temperature. In this experiment, acetanilide was produced by acetylation of aniline with acetic anhydride. The crude acetanilide was dissolved in a solvent in a heating water bath. The solution was cooled slowly in an ice bath as crystals form out. As the compound crystallizes from the solution, molecules of other compounds dissolved in solution are excluded from growing crystal

Air Quality Monitoring in Memphis and Surrounding Areas in 2014, Analyzed by Gas Chromatography/Mass Spectrometry (GC/MS) By Ebtsam Seteh Abstract Volatile organic compounds (VOCs) in the atmosphere have been determined to be a human risk factor in urban, suburban, and industrial environments. This study aims to characterize the distribution and concentrations of ambient air toxics in Memphis and identify major sources of VOCs. During four seasons in 2014, about 530 ambient air samples
CHEM 1211 L Principles of Chemistry Lab 16 February 2004 Lab Report 1 Introduction The purpose of this project is to identify an unknown organic acid (X) by conducting various experiments to determine the acid’s unique properties. By determining selected constant properties of the unknown and then comparing these properties to the constant properties of known substances, it is possible to identify an unknown substance. The properties used to identify the unknown must be intensive, or independent
Summary The Aracuo mill in Sault Ste Marie manufactures a range of medium density fibreboard (MDF) composite panels as well as a wide selection of thermally fused laminates (Arauco, 2016). The resin based adhesives used in the manufacturing process of these materials create a source for airborne formaldehyde in the workplace. This presents a substantial health concern for workers in the Sault Ste. Marie Facility. Subsequently, routine air sampling is conducted to ensure safe working conditions.

Biology 100 Lab Laboratory Report Title: Identifying the four major classes of macromolecules through various tests. Group Members: Antonia Johnson, Payton Ewing, Lenneisha Hepburn, Kendisha Hanna, Introduction: Macromolecules also known as biological molecules are monomers which are the simple units of polymers. All macromolecules contain carbon and hydrogen which are found in organic compounds. In this Experiment we will test for the presence of protein, starch, lipids, and sugars by analyzing
potential energy is the result of electrostatic attractions between atoms. C3.3: Heating Impacts Heating increases the kinetic (translational, rotational, and vibrational) energy of the atoms composing elements and the molecules or ions composing compounds. As the kinetic
