You have a one liter solution of kerosene containing 25 wt% propionic acid, add one liter of water, mix thoroughly and allow the two phases to settle. At this temperature, the distribution coefficient for propionic acid is 0.175 mass fraction in kerosene/mass fraction in water. What is the expected composition (wt%) and mass (kg) of the two phases? You may need to acquire physical properties for some of your species.

An analytical chemist is titrating 227.3mL of a 1.200M solution of propionic acid HC2H5CO2 with a 0.5600M solution of NaOH . The pKa of propionic acid is 4.89 . Calculate the pH of the acid solution after the chemist has added 532.8mL of the NaOH solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of NaOH solution added. Round your answer to 2 decimal places.

Nicotine is to be extracted with kerosene from a water solution containing 1% nicotine. Water and kerosene are essentially immiscible. The equilibrium of a solute between immiscible solvents is expressed by the distribution coefficient, K, which is the ratio of the solute concentration in the two phases and for the distribution of nicotine between kerosene and water K = 0.9. Calculate the percent extraction of nicotine if 100 kg of feed solution is extracted once with 150 kg solvent.
