The purpose of this experiment is to prepare a Grignard reagent by reacting with alkyl or aryl halide and to ultimately react the Grignard reagent with carbon dioxide in order to produce carboxylate. The formed carboxylate is then protonated with an acid to produce carboxylic acid that could be used with liquid-liquid extraction to isolate the unknown acid from the other products from side reactions. The final unknown product is identified by measuring the melting point and calculating the molecular

CuSO4, and 2.0153 grams of iron powder, Fe. The goal of this experiment was to determine the product of copper (II) sulfate with iron. The reaction occurred and 2.4469 grams of solid copper, Cu, precipitated; therefore, showing that the limiting reagent was iron. The iron oxidation state was iron (II) because iron (II) sulfate was formed during the reaction. The percent yield of the reaction was 106.7%. Introduction Literature sources The purpose of this lab was to use techniques of quantitative
specify that each reagent is to be used within its expiration date, and will not be used past this date unless there is a legitimate reason for its continued use. It then goes on to specify that all reagents will follow at least American Chenical Society guidelines for reagent grade chemicals and what chemicals the lab uses. Finally, all chemicals will be checked prior to any case, recorded in the case notes and in the Reagent Daily Use Verification Logbook, & will be replaced if the reagent cannot be used
Triphenylmethanol John Kang Chem 152L Performed: 7/20/04 Date submitted: ________________ Lab Partners: Sang Lee, Vicky Lai TA: John Stanko Abstract: This experiment explored the synthesis of triphenylmethanol through the use of Grignard reagents. The percent yield of the product was 10% on a relatively humid day. The melting point was calculate to be 127.2oC with a literature value of 162oC. An IR spectrum of the product was taken and used for positive identification of the product.
Examination - Advanced Level Chemistry (Salters') - Paper 3 mock. ROBERT TAYLOR U6JW. A Catalyst is a substance that alters the rate of a reaction. The catalyst remains unchanged at the end of the reaction. The process is called catalysis. In this report I aim going to explain the role of catalysts in chemical reactions and their importance in industry. I will also outline the problems associated with the use of some catalysts and discuss, using appropriate examples, new developments in this area
Copper-Iron Stoichiometry Lab Report 10/3/12 Abstract: The lab performed required the use of quantitative and analytical analysis along with limiting reagent analysis. The reaction of Copper (II) Sulfate, CuSO4, mass of 7.0015g with 2.0095g Fe or iron powder produced a solid precipitate of copper while the solution remained the blue color. Through this the appropriate reaction had to be determined out of the two possibilities. Through the use of a vacuum filtration system the mass of Cu was
The same can be done for processing costs. Pricing information for the consumables used is available from the utilization reports generated monthly by the finance department. When calculating reagents costs, the cost of the reagent actually used to run a single test is easy to calculate based on the known volume of reagent used and the cost per volume. These numbers are available from information generated by vendors. The cost of calibrators and controls is also available
Chemical Composition of Cells Lab Report Tyler Thomason September 14, 2015 Introduction A cell, the building block of all living organisms, is composed of four fundamental biomolecules: proteins, carbohydrates, sugars and lipids. Proteins provide a vast amount of functions cells such as they serve as enzymes, provide structural support to cells, and act as antibodies. Reagents are used to spark a chemical reaction. The reagent used to detect protein traces in a
1.0 INTRODUCTION With approximately 25 million tonnes of steel making coal produced in 2013, Teck Coal Limited is the largest producer of steelmaking (coking) coal in North America and the second largest exporter of steelmaking coal with approximately 95% of the coal produced being exported to various countries in Asia, Europe and South America. China, Japan & Korea form the bulk of the countries who import steelmaking coal from Teck Coal Limited (Teck Resources Limited, 2013). Figure 1 below shows
