The weak acid HA with a dissociation constant Ka is distributed between and organic solvent and water. If the only extractable species is the undissociated species HA with a partition coefficient K, derive an expression showing the dependence of the distribution ratio, D, on [H+] of the aqueous phase and draw conclusions from this expression.

A 0.035 mol sample of a weak acid, HA, is dissolved in 601 mL of water and titrated with 0.41 M NaOH. After 33 mL of the NaOH solution has been added, the overall pH = 5.281. Calculate the Ka value for the HA. Let’s write out the acid dissociation: HA ↔ A– + H+ Ka=??? Now, if we add NaOH (strong base), it will react with the HA (acid). So let’s construct an ICE table in moles to find...
