The partition coefficient of iodine between CCl4 and water is CCC14/CH20 = K = 85, where the C₁ represent the concentration in mol/L of iodine in the solvent. (a) If you want to extract 90% of the iodine from 100 mL of an aqueous iodine solution in a single extraction, Calculate the volume of carbon tetrachloride needed. (b) If you want to extract 90% of the iodine from 100 mL of an aqueous iodine solution in two extractions of equal volumes, calculate the volume of carbon tetrachloride needed in each. (c) If ß is the fraction of iodine remaining in the aqueous solution after n extractions with equal volumes of CC14, show that as n → ∞, the total required volume of CCl4 per unit volume of water for each extraction is given by:

Question
The partition coefficient of iodine between CCl4 and water is Сcc14/CH₂0 = K = 85, where the C₁ represent the concentration in mol/L of iodine in the solvent. (a) If you want to extract 90% of the iodine from 100 mL of an aqueous iodine solution in a single extraction, Calculate the volume of carbon tetrachloride needed. (b) If you want to extract 90% of the iodine from 100 mL of an aqueous iodine solution in two extractions of equal volumes, calculate the volume of carbon tetrachloride needed in each. (c) If ß is the fraction of iodine remaining in the aqueous solution after n extractions with equal volumes of CC14, show that as n→ ∞, the total required volume of CCl4 per unit volume of water for each extraction is given by: Remember that: ln(1+x) ≈ x 2 VCC4,tot VH₂0 + 몰.... 3 In 3 K
