The purpose of this lab was to study the four main types of chemical reactions, and describe these reactions using balanced chemical equations. This lab was done in an open classroom with air circulating vents, safety goggles were worn, long hair was tied up, and sleeves were rolled up. This lab was divided into seven different stations, each of which studies a different chemical reaction. The first station included copper (II) sulphide penta-hydrate, which was burned in a test tube using a Bunsen…

SYNTHESIS AND CHEMISTRY OF K2S2O8 ABSTRACT In this experiment, a sample of K2S2O8 was prepared by the electrolysis of an aqueous solution of H2SO4 and K2SO4. The peroxodisulfate anion, S2O82-, was also observed for its ability to serve as a counterion for precipitation by preparing a copper (II) complex by reacting hydrated copper (II) sulfate with ammonium peroxodisulfate in the presence of pyridine. This same ability, coupled with its strong oxidizing ability allowed for stabilization of…

Amanda Tran Date of lab: 04/25/05 Date submitted: 05/09/05 Chem 2130-3 Experiment 3: Synthesis of Co(acac-NO2)3 Introduction In this lab, Co(acac·NO2)3 is synthesized using the Co(acac)3 complex produced in Experiment 2. The Co(acac)3 complex is used as a reagent instead of acacH because acacH cannot be directly converted to 3-nitroacetylacetone. Since Co(acac)3 is not stable in HNO3, Cu(NO3)2 and acetic anhydride are used in this reaction to produce the final product…

Synthesis of Phenacetin Compare/Contrast Purpose: The purpose of this laboratory report was to evaluate the similarities and differences between Acetaminophen and p-Phenetidine, which were both synthesized from Phenacetin. Through the research that was conducted in the laboratory, one will learn about two different drugs, which was synthesized from Phenacetin. By forming crystals from the Phenacetin, tests for NMR, IR, and melting point was able to be conducted. These tests will allow the reader…

CHEMISTRY REVISION Periodic table * All the elements on the Earth are on the Periodic Table. * They are arranged according to patterns in their properties e.g. The masses of their atoms * The relative atomic mass is the mass of an atom in relation to hydrogen e.g. Helium has an atomic mass of 4 which means it has 4x the mass of hydrogen * Each period starts with a metal and ends with a non-metal Alkali metals * The alkali metals (Group 1 in the periodic table) are Lithium…
