In the extraction of salicylic acid from water using dichloroethane, a student begins with 2.9 grams of the salicylic acid dissolved in 100 ml of water. After extraction with 20 ml of dichloroethane, drying and evaporation of the organic layer yielded 1.972 grams of salicylic acid. Assuming the student was efficient and did not lose any material, what is the distribution coefficient (Kd) for the system ?

let Kd = (concentration in organic solvent) / (concentration in aqueous solvent)
a. 4.25
b. 10.63
c. 12.22
d. 6.91
e. 9.57

    Extraction of benzoic acid and 9-fluorenone using diethyl ether. (please do not include ethyl 4- aminobenzoate). I have to create a flow chart to diagram the key steps of the experiment and isolation of products. 0.100g of benzoic acid and 9-fluorenone are dissolved in diethyl ether. The extraction solvent is 5% sodium hydroxide (to extract the acidic component from the organic phase). Saturated sodium chloride is added to the organic layer. drying the organic solution: anhydrous sodium sulfate is added...

    The student dissolved 2.050 grams of acid in 50 mL of distilled water. He then titrated the unknown acid with a standardized NaOH solution. Unfortunately, the student over shot the end point and had to back titrate the solution with 2.17 mL of 0.98861 M HCl. Once the final end point was determined, the student had added a total of 29.15 mL of a 1.0324 M NaOH solution. A) How many moles of OH- were used to reach the end...

    Pre-lab Questions: Importance A one-step preparation of aspirin from its precursor, salicylic acid, via an ester formation illustrates one of synthetic organic chemistry's most important uses, making the drugs that treat all types of illnesses. OH HOOH Background Aspirin is a prodrug of salicylic acid, the actual active drug. A compound related to salicylic acid, salicin, was first isolated from willow bark in the mid 1700's, but willow-bark extract was used by the ancient Greeks as a treatment for pain...
