- Procedure: analytically transfer between 0.4053g of iron(III) chloride hexahydrate, FeCl 3•6 H2O (M = 270.2957g•mol-1), and dissolve in 5.5 mL distilled, deionized water. Support the tube on a stir plate and over a 15-minute period add, using the 10mL burette, 5mL of a nominal 600mM solution of 2,4 pentandione in methanol under constant stirring. To the resulting solution, add via a 10mL burette 3mL of a nominal 450mM sodium acetate solution stirring constantly. At this point, a red crystalline solid should begin to precipitate. Transfer and support the reaction vessel in the hot water bath and once the reaction mixture has reached a stable temperature in the desired range, maintain the reaction mixture at this temperature, under constant stirring, for a 15-minute period Initial weight of iron(III) chloride hexahydrate: 0.4053g The final weight of the reaction tris(acetylacetonate)iron(III): 19.6 mg 3. What is the charge on the metal in the starting material for your synthesized…Carboxylic acids, including fatty acids and benzoic acids, are often present inboth municipal and industrial effluents. Describe a sample preparationcombined with GC method for identification and determination of carboxylicacids in raw wastewater at ppb (µg L-1) level. Point out a suitable samplepreparation technique and GC conditions in details and give justifications foryour choiceYou are employed as a coop student at the Drug and Alcohol Testing Association of Canada (DATAC) developing analytical tests for sports doping agents. You are asked to prepare a procedure for the extraction of methylphenidate, the active compound in Ritalin, from urine samples (consider them as simple aqueous layers, you do not need to consider other components!). The goal of the procedure is to extract the methylphenidate into an organic layer which will then be evaporated, and the residue will be tested for the drug.You find that methylphenidate is highly soluble in 2-methyltetrahydrofuran, a bio-renewable solvent. Draw the structure of 2-methyltetrahydrofuran and give two reasons why it is a good solvent choice for liquid-liquid extraction.
