Solute W has a distribution coefficient of 1.0 between water and ether. 320 mg of W are dissolved in 10 ml of water. If this solution is extracted five times with 10 ml of ether. How much of solute W will be in the combined organic phase?
Suppose solute A has a distribution coefficient of 1.0 between water and diethyl ether. Demonstrate that if 4.0 mL of a solution of 0.20 g of A in water were extracted with two 1.0-mL portions of ether, a smaller amount of A would remain in the water that if the solution were extracted with one 2.0-mL portion of ether.
Organic Chemistry You have 1.00g of your organic product dissolved in 50 mL of water. The distribution coefficient of this compound in ether and water is 5. How much of your compound would be extracted by one 60 mL portion of ether? How much would be extracted if you used three 20 mL portions instead? (Show your work!!)
The solubility of compound A ịn water at 25°C is 3.00 g/100 mL. In benzene at the same temperature, the solubility of compound A is 4.00 g/50mL. If 3 g of compound were dissolved in 100 mL of water, how much compound would be extracted by three 10-mL portions of benzene?
The extraction of 8.0 g of a particular organic compound dissolved in 100 ml of water into diethyl ether proceeds with a distribution coefficient of 5. How much of the compound is extracted after three separate extractions using 50 ml of diethyl ether each time? ***Please show work as I am not 100% sure how to solve for X**** Thank you!
In this experiment, 0.170 g of caffeine is dissolved in 10.0 mL of water. The caffeine is extracted from the aqueous solution three times with 5.0-mL portions of methylene chloride. Calculate the total amount of caffeine that can be extracted into the three portions of methylene chloride (see Technique 12, Section 12.2). Caffeine has a distribution coefficient of 4.6 between methylene chloride and water.In this experiment, 0.170 g of caffeine is dissolved in 10.0 mL of water. The caffeine is...
Assume an organic compound has a partition coefficient between water and ether equal to 8.48. If there are initially 7.52 grams of the compound dissolved in 70.0 mL of water, how many grams will remain in the aqueous layer after extraction with two 25.0 mL portions of ether? Mass: ________ g
The distribution coefficient between methylene chloride and water for solute Y is 9. An amount of 125.0.0 g of Y is dissolved in 160 mL of water. a) What weight of Y would be removed from water with a single extraction with 160-mL of methylene chloride? Report to 1 decimal place. b) What weight of Y would be removed from water (the original solution with the original amount) with two successive extractions with 80-mL portions each of methylene chloride? Report...
0.070 g of caffeine is dissolved in 4.0 mL of water. The caffeine is extracted from the aqueous solution three times in 2.0 mL portions of methylene chloride. Calculate the total amount of caffeine that can be extracted into the three portions of methylene chloride. Caffeine has a distribution coefficient of 4.6, between methylene chloride and water.
Extractions rely on differences in solubility of the components that are being separated. The amount of a material that will transfer into the solvent in an extraction can be calculated using a partition coefficient. This is a ratio of the solubility of the material in each solvent that can be used to predict outcomes of extractions. A certain organic compound, Z, has the distribution coefficient (partition coefficient), Kp = 10.45 when partitioned between ether and water. Therefore, the equation used...
