An important parameter is called the octanol-water partition coefficient, Kow, which is related to the tendency of molecules to accumulate in fat tissue. Consider Benzene, for which the octano-water partition coefficient is 135. Suppose you do extractions from a 75.0 mL sample of water containing.250g/L of benzene. a) What is the concentration (g/L) of benzene remaining in the water after 1 extraction using 10.0ml portions of octanol? b) how much octanol would you need per extraction, to remove 99.99% of...
Organic chemistry question 4. Benzoic acid is almost 12 times more soluble in dichloromethane than in water at room temperature (the distribution coefficient (K) is 11.7). a) Approximately how many grams of benzoic acid would be recovered in the organic layer if 10.0 g of benzoic acid dissolved in 100 mL of water was extracted with 100 mL of dichloromethane? Show calculations. b) Approximately how many grams of benzoic acid would be recovered if the water layer was extracted a...
Suppose that you have a reaction mixture which consists of 13.2 g of KBr and 11.0 g of an interesting organic compound dissolved in 100 mL of water. You would like to have the pure organic compound, separate from water and salt, so you decide to carry out an extraction. You add 100 mL of dichloromethane and vigorously shake in a separatory funnel Suppose that instead of one extraction with 200 mL, or two extractions with 100 mL, you had...
Solute A has a partition coefficient K = 2 for an extraction between water (phase 1) and benzene (phase 2). If 100 mL of a 0.01M solution of A in water is extracted one time with 300 mL benzene, what fraction will be extracted?
