Question 4 3 pts The partition coefficient of a compound between two liquid phases is 4.43. If the starting volume of phase 1 is 13.00 mL, what total volume, in ml, is needed of phase 2 to realize 0.99 % in 3 extractions? Question 5 1.25 pts Using isocratic conditions (default) and nitrobenzene as an example, decreasing the particle size by a factor of 2 roughly increases number of theoretical plates by a factor of 2. False True Question 6 1.25 pts Using isocratic conditions (default) and butylparaben as an example, increasing the column length by a factor of 2 increases the number of theoretical plates by a factor of 4. True False
