Q: 2: An acidic solute, HA, has an acid dissociation constant of 1.00 x10-, and a partition coefficient between water and benzene of 3.00. Calculate the extraction efficiency when 50.00 mL of a 0.025 M aqueous solution of HA buffered to a pH of 3.00, is extracted with 50.00 mL of benzene. Repeat for cases in which the pH of the aqueous solution is buffered to 5.00 and 7.00.

Q: 2: An acidic solute, HA, has an acid dissociation constant of 1.00 x10-5, and a
partition coefficient between water and benzene of 3.00. Calculate the extraction
efficiency when 50.00 mL of a 0.025 M aqueous solution of HA buffered to a pH of
3.00, is extracted with 50.00 mL of benzene. Repeat for cases in which the pH of the
aqueous solution is buffered to 5.00 and 7.00.
