Lab report: Denzoic Acid

At Vrk#ecFaclb;TUnInSAlthough the purpose of this experiment was to investigate the recrystallization of Denzoic Acid, there were several graphical errors in the data. These errors affected the accuracy of the melting point values. Please refer to the attached document for detailed instructions on how to interpret the experimental data.

Post-Lab Questions 3: THE EMPIRICAL FORMULA OF A COMPOUNDConsider the following deviations from the experimental procedure: Explain how each of these deviations specifically affects the mass of the copper recorded (increase/decrease/stay the same)? Note: single word, not an explanation.1. The student did not wait for the blue color to disappear but continued and collected the precipitated copper by vacuum filtration.2. Copper remained in the beaker during the transfer to the Buchner funnel.3. The copper on the filter paper was not dry when the final mass was recorded.

In an experiment, a student isolated 6.356 g of pure copper from an initial sample of 9.902 g of a copper chloride compound. Determine the empirical formula of this compound (show your work).

Answer:How many grams of carbon are there in 835.801 g of formaldehyde; CH2O, which is 40.09 u carbon by mass (show your work)?

Experiment 19 Prelaboratory Assignment: Aspirin Synthesis and AnalysisName: Desk No: Date: Lab Sec:Procedure, Part A:In the experiment, 2.00 g of salicylic acid (molar mass 138.12 g/mol) reacts with an experimental excess amount of acetic anhydride. Calculate the theoretical yield of acetylsalicylic acid (molar mass 180.2 g/mol) for this synthesis.

After completing the experimental procedure, a mass of 1.78 g of acetylsalicylic acid was obtained. What is the actual yield for its synthesis? Express the yield with the correct number of significant figures.

Experimental Procedure, Part B:Recrystallizing Medium:Explain how to perform the recrystallization of the product obtained in Part A.

POST-LAB QUESTIONSCalculate the total mass percent of the copper compound.The total mass % of the copper compound is 0.0259%.Calculate the total mass percent of the cobalt compound.The total mass % of the cobalt compound is 0.013g.Calculate the total mass percent of the chromium compound.The total mass % of the chromium compound is 0.0179%.Assuming you had correctly followed the experimental procedure, what could be a possible reason why the combined percentage of the compounds decreased during the extraction and isolation procedures?In addition, state how this reason could possibly be mitigated.One possible reason for the decrease in the combined percentage of the compounds during the extraction and isolation procedures is that some of the compounds may have been lost or left behind during the process. This could be mitigated by ensuring that all equipment and containers are properly cleaned and that the extraction and isolation procedures are carried out carefully and accur…
