Explain exactly what you would do when performing the following laboratoryinstructions; that is, write a short procedure.a. “Wash the organic layer with 1.0 mL of 1 M aqueous sodium bicarbonate.”b. “Extract the aqueous layer three times with 1-mL portions of methylenechloride.”

What is magnesium sulfate used for at the end of the extraction? How can it be removed?

A student following the published Experiment 5 procedure mixes 1.702 g 4-aminophenol with an 2.6 mL acetic anhydride.  Calculate the moles of 4-aminophenol used.  Use the formula weights and density (if needed) provided in the procedure.  Report your answer to 3 significant figures.

If 80% of a desired compound is extracted into the organic phase in each step (leaving 20% in the aqueous layer), how many extractions are necessary to ensure that at least 99% of the compound has been recovered in the organic phase?      1 extraction     2 extractions     3 extractions     4 extractions

what is the balance equation wirh physical sates of butanoic acid and potassium butanoate as buffer solution.

Regarding an organic chemistry laboratory experiment: a. In this experiment, the distillate is initially extracted with diethyl ether (Et2O). Provide two important safety issues regarding the use of diethyl ether. b. Eugenol is a phenol (i.e., an aromatic alcohol). Why is diethyl ether used to extract it from the distillate rather than ethanol?

You are asked by your chemistry teacher to find: a) the solubility of different carboxylic acids in water and b) whether there is a connection between solubility and structure of different carboxylic acids. Follow the questions below to design and conduct an experiment to determine an answer to this question. a. From the paragraph above, write a question out that you will try and answer from conducting an experiment (C:2) b. Based upon your knowledge of the physical properties of organic compounds, hypothesize an order of solubility from lowest to highest: (1:3) Organic Compound Order of solubility (1=lowest, 3=highest) Pentanoic acid Hexanoic acid Ethanoic acid c. Provide an overall explanation for your hypothesis based upon your knowledge of physical properties. (A:3) d. Based upon the materials listed below, design a step by step experiment to test your hypothesis. Provide your individual steps. Include all the materials listed below. (1:3) Materials: CH,(CH,4COOH (), CH,COOH (),…
