How do i determine the distribution coefficent of benzoic acid? I used 0.050 grams of benzoic acid and performed extractions 3 times using 2.0 ml of methylene cloride and 2.0 mL of water and got around 0.035 grams after all the extractions done. also is there a correlation between the values of the distribution coefficent and the polarity of the compound? thank you

You need to make a benzoic acid-based buffer that has a ph of 5.10. The volume should be 500ml. What masses of the acid and its conjugate base should you use? (Hint: you should not go over 1M in concentration for either acid or conjugate base) Show all Work. Part B. The pH of the above buffer solution should not go above 5.15. If 10ml of 0.1 M NaOH is added to the buffer, will the pH go past the...
