  2. Calculations • If Kd = [organic phase]/[water phase] = 8.0 • Calculate the fraction of a sample left in the water phase after 3 individual separations. The sample that is left in the water phase. • Awater Aorganic phase 1-x x [x] /[1-x] = 8.0 9x = 8.0 x = .89 0.11 left 11.0 % left

  3. Awater Aorganic phase 0.11 – x x Kd = x/0.11-x = 8.0 9x = 0.88 X = 0.098 0.012 left 1.2 % left Awater Aorganic phase 0.012 – x x Kd = x/0.012-x = 8.0 9x = 0.096 X = 0.0107 0.0013 left 0.13 % l3ft
