Q: 1: The distribution constant for iodine between an organic solvent and H,0is 85. Find the concentration of I; remaining in the aqueous layer after extractionof 50.0ml. of 1.00 x 10 M I with the following quantities of the organicsolvent: (a) 50.0 ml.; (b) two 25.0 ml. portions; (c) five 10.0 ml. portions.Q: 2: An acidic solute, HA, has an acid dissociation constant of 1.00 x10, and apartition coefficient between water and benzene of 3.00. Calculate the extractionefficiency when 50.00 ml. of a 0.025 M aqueous solution of HA buffered to a pH of3.00, is extracted with 50.00 mL of benzene. Repeat for cases in which the pH of theaqueous solution is buffered to 5.00 and 7.00.
