Answer / trevor molyneux
There are number of possibilities for identifying the
eluents from the column. Try passing the eluent through a
UV beam if any of the eluents fluoresce. You could also
pass the eluent through a set up with an IR source and
detector or a refractive index measuring instrument. Any
of these alternatives could be used quantitatively.

2. Two grams of Benzoic acid are dissolved in 200 ml of water and extracted with 200 ml of diethyl ether. The distribution coefficient of benzoic acid is 100, and its dissociation constant is 6.5 10-5. Calculate the distribution ratio (D) of benzoic acid at pH 2, 5, and 6. 3. Calculate D at pH 2 to 10 (1 unit apart) in the above problem, and plot D versus pH.
