Analysis of Oxygen bearing Organic compounds Abstract The Unknown sample in the experiment can be tested to yield results such as 1° (primary)‚ 2° (secondary)‚ 3° (tertiary) alcohols. Tests such as the dichromate test‚ Tollen’s test‚ Lucas test‚ DNPH test and iodoform test would be very useful in determining the type of alcohol that the unknown sample belongs to. In the experiment‚ the unknown sample underwent series of testing to identify what property of alcohol it belonged to and the result

Introduction and Background A multi-division corporation had a small plastic piece fail in one of its specialty machines. The maintenance department has been asked to replace the part. However‚ the original manufacturer‚ Kaufmann Ltd.‚ has gone out of business‚ and specifications for the part are unavailable. The purpose of this experiment‚ performed by Ryan Nelson‚ Peter Glascor‚ Eric Flowr was to determine the identity of the unknown polymer by comparing its properties to properties of other

Lab Report 2: Quantitative Analysis Finding the Percentage Composition of Nickel in an Unknown Compound Introduction: This section of lab was about using analytical chemistry and learning how to identify the amount of nickel in an unknown substance. The purpose was to use gravimetric analysis to quantitatively separate and weigh insoluble reaction products as well as utilize the mole method to compute the amount and percentage of nickel in an unknown nickel sample. The chemical reaction that took

In order to recrystallize the caffeine‚ we used a mixed-solvent method‚ consisting of hot acetone and hexanes. The solution was cooled and a vacuum filtration was done to remove the caffeine crystals. The final product weighed about 3 mg. Introduction Caffeine is an organic compound that is found in tea leaves and coffee beans. It is a basic

Lab #4 The Synthesis of Organic Polymers CHM2123‚ Section C October 21‚ 2014 Introduction: Organic polymers are macromolecules that are composed of smaller molecules called monomers. There are two main groups of polymers: natural polymers and unnatural (synthetic) polymers. Natural polymers include proteins such as cellulose and starch and are a necessity for our existence. On the other hand‚ synthetic polymers such as the polycarbonate in our lab goggles
