which is a Grignard reagent, and benzaldehyde which is a carbonyl group. The goal of this experiment was to investigate the ability of the Grignard reaction to yield the theoretical predicted product and evaluate its efficiency. The Grignard reaction is an important reaction because of its ability to allow the formation of carbon-carbon bonds. These formations of C-C sigma bonds, then allow for the formation or making of large or complex synthetic molecules from very simple reagents. These complex molecules

thermodynamically stable than the product; in this case, methyl salicylate was less stable than the salicylic acid. Heating was performed under reflux7. In this experiment, the reagent that was fully used when the reaction completed and limited the amount of product formed was the methyl salicylate, making it the limiting reagent. Determining the theoretical mass and volume of methyl salicylate required for the use of 5 mmol of methyl salicylate prior to experimental procedure served to set an ideal

veterinarian clinics. Omnivue is one of the most successful equipments produced by the company, which is priced at a competitive rate to attract lower and middle sized veterinarians. The production of Omnivue involves the use of plastics and chemical reagents supplied by two major suppliers, GenieTech and Elsinore. The management of Bergerac is planning to take control over its suppliers to reduce the production fluctuation and overhead costs of the firm. There are three strategic

is the principle of when a stress is applied to a chemical system at equilibrium, the equilibrium will shift to relieve the stress. The experiment was designed to test the effects on the equilibrium when other substances were added to the reagents. The reagents were observed and recorded. The shift of the equilibrium was determined to further understand the factors that affect the chemical equilibrium. Procedures: In this experiment, Iron(III) nitrate (Fe(NO)3) and Ammonium thiocyanate (NH4NCS)

test, Biuret test, Paper test on various foods such as banana, coconut milk, whole milk, peanut and potato as to what type of macromolecules (sugar, protein, starch, lipid) they have. I have come to a conclusion that when a reagent (Benedict’s reagent, Iodine reagent, Biuret reagent) was mixed with any type of solution, there is a reaction/ effect that takes in place once there is a presence of any type of macromolecule. INTRODUCTION: In this laboratory, we will study three classes of the largest biological

This section documents the procedure used to define PCQLs for those analytes for which spiking solutions or quality control samples are not commercially available. If such solutions become available, their use will be documented in the relevant SOPs, and any PCQLs that are based on them will supersede the following values. Acidity: Acidity is determined by empirically subtracting the value of a titration with H2SO4 from the value of a titration with NaOH. Depending upon client request, the result

This experiment aimed to investigate the relationship between temperature and reactant concentration on the rate of reaction for the hydrolysis of tert-Butyl Chloride, and to determine the validity of the proposed mechanism for the reaction. It was hypothesised that measuring the kinetics of this unimolecular substitution reaction would demonstrate the reaction rate for the hydrolysis of tert-Butyl Chloride utilising acetone as the solvent which should increase with both its increased concentration

Standard Methods for the Examination of Water and Wastewater 5210 BIOCHEMICAL OXYGEN DEMAND (BOD)*#(1) 5220 CHEMICAL OXYGEN DEMAND (COD)*#(2) 5220 A. Introduction Chemical oxygen demand (COD) is defined as the amount of a specified oxidant that reacts with the sample under controlled conditions. The quantity of oxidant consumed is expressed in terms of its oxygen equivalence. Because of its unique chemical properties, the dichromate ion (Cr2O72–) is the specified oxidant in Methods

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

Copper in Silver Nitrate Lab: Making Silver Sabrina Kate S. Carranza – Chemistry Hour 6 I. Purpose: The purpose of this experiment is to distinguish the relationships between reactants and products, in addition to expanding on concepts such as single displacement reactions, mole ratio values, moles to mass, theoretical yields, limiting reactants, excess, stoichiometric relationships and percentage errors. II. Hypothesis: /3 -If the copper metal is submerged in the silver nitrate solution
