Deborah Bell April 17‚ 2012 Chemistry 1212K Lab Synthesis Report Introduction In this Chemistry Lab the main objective is to perform accurate chemical analysis for the quantity of elements and compounds in a sample. There will be a compound made then synthesized. The methods used were acid-base titrations‚ redox titrations‚ gravity filtration‚ and distillation. General conclusions included Procedures Weight of Crucibles 1. The first experiment is Preparation of a Cobalt Amine

Lab report is one way we used during of after an experiment in a laboratory to subtly record and discuss the experiment. During a lab‚ we sometimes can observe only the physical part of the experiment‚ or may be some visible chemical changes. These changes indicate that the experiment we do is successful or not. However‚ in order to understand and achieve more from just simply doing the experiment‚ we write lab report to more profoundly understand the internal meanings of the experiment we do‚ and

important in determining whether a reaction will produce a precipitate. Starting out the experiment‚ HCl was added to the solution in the test-tube in order to form a reaction between the HCl‚ Ag‚ Pb‚ and Hg cations. The products of this addition of HCl were PbCl2‚ AgCl‚ and Hg2Cl2. After the HCl was added‚ the solution turned a milky white color. It was important to not add too much HCl because excess HCl would have caused an aqueous complex of PbCl2 and AgCl to form instead of the desired solid PbCl2

Chemistry 101 12-STANDARDIZATION OF SODIUM HYDROXIDE Standard solutions for titrations are especially pure mixtures with exactly known concentrations. Primary standards are very pure solids. They have the advantage that they can be weighed (the analytical balance is normally the most accurate instrument in the laboratory) and they are stable under laboratory conditions. In this experiment‚ the primary standard is oxalic acid dihydrate‚ H2C2O4 ( 2H2O. It will be used to standardize a

Chem 105 Guide to the Formal Laboratory Report The purpose of a formal report is to communicate effectively to another person the goal‚ procedure‚ data analysis method‚ and results of your laboratory work. The report is divided into several well-defined sections. Each section must be present in a complete report. To earn an outcome point for the laboratory report‚ a student must submit a formal lab report that earns a score of at least 90/100. Each error (factual‚ grammatical‚ typographical

Standardization is the process by which a company makes it methods‚ especially its production processes‚ uniform throughout its organization. Standardization helps cut costs by eliminating duplicated effort and allows a company to take advantage of economies of scale when purchasing supplies. However‚ some advantages may be lost when a company decided to standardize its operations. Disadvantages Loss of Uniqueness If a company builds up a customer base that values its unique niche products‚ or
