CHEM 2123 and 2125 – Organic Chemistry Lab I and II GUIDELINES FOR WRITING LAB REPORTS INTRODUCTION Writing reports in organic chemistry lab may differ from the way it’s done in general chemistry. One goal of this course is to introduce you to the record keeping methods used in research labs. Such methods are designed to organize experimental data in a format similar to that required for publication in major scientific journals. Here are some important considerations that apply in research settings

Separating Acids and Neutral Compounds by Solvent Extraction Introduction The purpose of this experiment was to use solvent extraction techniques in order to separate a mixture consisting of a carboxylic acid (p-toulic acid), a phenol (p-tert-butylphenol), and a neutral compound (acetanilide). Extraction is the process of selectively dissolving one or more of the compounds of a mixture into an appropriate solvent, the solution that contains these dissolved compounds is called an extract (Manion

Should We Mine This Ore? Names CHM113 TA Name Class Time Introduction One of the most important skills to have in the chemistry lab is the understanding of how chemicals will react. Knowing for example, how a chemical will react with a metal, is an excellent way of determining the amount of a particular metal in a deposit. This knowledge was used in this lab to determine the amount of copper in an unknown sample mixture. It is also known that the determination of the percent concentration

have learned: 1. The law of conservation of mass. 2. How to calculate an empirical formula. 3. The concept of limiting reagents. Introduction Synthesis and the determination of empirical formulas are two extremely important parts of chemistry. In this experiment, you will synthesize zinc iodide and determine its empirical formula. The molecular formula gives the actual number of atoms of each element in the molecule and the empirical formula gives the lowest whole number ratio of the

Thermochemical heat storage can be physical (sorptive) or chemical based on the material used. The storage system which does not involve the production of new compound is called sorptive storage while those which involve formation of new compound are called chemical storage. The successful thermochemical storage system is sorptive storage system that works on utilizing the heat of reaction enthalpy. Thermochemical storage has considerable benefits when compared to sensible and the latent-heat thermal

Bioluminescence in Fungi INTRODUCTION What is Bioluminescence? The current paper main focus is on bioluminescent Fungi but the basic features of bioluminescence discussed are common to all bioluminescent organisms. Bioluminescence is simply light created by living organisms. Probably the most commonly known example of bioluminescence by North Americans is the firefly, which lights its abdomen during its mating season to communicate with potential mates. This bioluminescent ability occurs in

In the book “ The Scientific Revolution: A Very Short Introduction”, Lawrence Principe discusses the general occurring events of the scientific revolution, and overviews various in-depth details in relation to those events. People at the time highly focused on the meanings and causes of their surrounds, as their motive was to “control, improve and exploit” (Principe 2) the world. In his work, Principe has successfully supported the notion that the Scientific Revolution stood as a period in time where

filled with the logic, excitement, and anomalies of chemistry. In the beginning, Oliver Sacks is fascinated with metals and their properties, largely influenced by his Uncle Dave, who is better known as Uncle Tungsten. He asks Uncle Tungsten, his parents, and many others, questions about anything that intrigues him typically with chemistry in mind. Throughout his boyhood, he is constantly learning and studying everything dealing with chemistry including the important men and women (heroes) that
