Question

(b) The partition coefficient of a base B (monoacidic) at a particular pH, in an octanol-water mixture is 1.45. Consider an experiment where 3.5 g of B are shaken with 100 mL of octanol and 50 mL of water. Molar mass of B = 101.19 g mol-1 (i) Calculate the mass of B in the aqueous layer after shaking. (ii) Calculate the volume of 0.5 M HCl required to neutralize the aqueous layer. (iii) If B was diacidic, how would this affect your answer in part (ii).

Step 1

Given: - Mass of B = 3.5 g - Molar mass of B = 101.19 g/mol - Volume of water = 50 mL Number of moles of B = Mass / Molar mass = 3.5 g / 101.19 g/mol = 0.0346 mol Number of moles of B in water = 0.0346 mol - 0.026 mol = 0.0086 mol Mass of B in water = Number of Show more…

The partition coefficient of a base B (monoacidic) at a particular pH, in an octanol-water mixture, is 1.45. Consider an experiment where 3.5 g of B is shaken with 100 mL of octanol and 50 mL of water: Molar mass of B: 101.19 g/mol Calculate the mass of B in the aqueous layer after shaking. Calculate the volume of 0.5 M HCl required to neutralize the aqueous layer. If B was diacidic, how would this affect your answer in part (ii)?
