Micelles and Biological Membrane

Micelles are the type of lipid molecules that organize themselves in spherical shape in aqueous solutions. The production of the micelle is a reply to the amphipathic behavior of fatty acids. It means that they consist of both hydrophobic regions and hydrophilic regions. In micelles, polar head groups (hydrophilic groups) produce an outer layer associated with water whereas nonpolar tails (hydrophobic groups) are organized in the interior.

Question

3) I need help with part B

Unlike strong acids and bases that ionize completely in
solution, weak acids or bases partially ionize. The tendency
to ionize (i.e., the ionic strength) of a weak acid or base can
be quantified in several ways including
Ka or K,
pKa or pKb.
and percent ionization.
