2:05 P.M. Purpose: The purpose of the experiment is to measure the densities of liquids. Specifically‚ the two liquids that were used and measured in the research were deionized water (H2O) and alcohol (C2H5OH). Methods: Density is an intensive quantity that cannot be visually identified. Therefore‚ the most straightforward approach to this problem was to record the measurements of mass and volume. For volume of each liquid‚ the instruments used were a 50ml burette‚ a 50ml graduated cylinder and a 10ml

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

flavors‚ molecules‚ caffeine‚ etc. are extracted from the coffee beans. In this experiment‚ a solution was extracted containing a known amount of benzoic acid in water with methylene chloride‚ an organic solvent. The amount of leftover acid was determined through the titration of the aqueous‚ not the organic‚ solution with basic NaOH. This allowed the student to calculate and determine the Kd value of both multiple and single extractions. The efficiencies of both single and multiple extractions were
