(1) In Co-analysis lab a sample of the cobalt compound weighing 1.1427 gram was heated until color change occurred followed by the addition of 10.0 mL of water, and 1.0 mL of sulfuric acid. The solution was transferred quantitatively to a 100.00 mL Volumetric flask, shaken and filled to the mark with water. A sample of this solution gave a percent transmittance reading...

Error Analysis Questions for Alum Synthesis Experiment 1. After collecting the alum product from the synthetic experiment, a chemist calculates a percent yield of 108.9%. What does this suggest regarding the purity of the resulting two possible reasons for such a high percent yield. 2. Assuming the sulfuric acid (H SO.) added is insufficient to fully react with all of the Al(OH),, how would this affect the theoretical yield of alum.

Synthesis and Analysis of a Copper Oxalate Complex (Formal Report) This is a 3-week experiment and it will be the basis for your formal report, details to follow. Coordination complexes are molecules or ions formed when a central metal ions form bonds to nonmetal ligands. These interactions are Lewis acid/base interactions where the metal ion acts as a Lewis acid and the ligand acts as a Lewis base. For example, a common coordination compound is the copper ammine complex [Cu(NH3),],...

Synthesis using Carbonyla-Substitution Chemistry Preamble This experiment involves the synthesis of target molecules using a-substitution chemistry. You are assigned two target molecules, one of which is best synthesized by an alkylation approach, while the other is best synthesized by an addition or condensation approach. My two target molecules are number 2 and number 12 in the last page. You must do the following: 1. Perform a retrosynthetic analysis on the two target molecules assigned to you. In each case the...

OH 4. A Chem 241 student was given an experiment to synthesize compound 1 from ethyl acetoacetate. The student prepared 1 mole equivalent of methylmagnesium iodide, co Et which was then slowly added to a solution of ethyl acetoacetate in ether. Everything went well; indeed, even without the application of heat, the reaction mixture bubbled merrily. Working carefully with supervision and advice from the lab instructor the student worked- up the reaction and isolated an excellent yield of the starting...
