Butanoic acid has a partition coefficient of 3.0 favoring benzene when distributed between water and benzene. Determine the formal concentration of butanoic acid in each phase when 100mL of 0.10 Maqueous butanoic acid is extracted with 25mL of benzene (a) at pH4.00 and (b) at pH 10.00.
The solubility of CO2 in water at 25°C and 1 atm is 0.034 mol/L. What is its solubility under atmospheric conditions. (The partial pressure of CO2 in air is 0.0003 atm.) Assume that CO2 obeys Henry's law.
