Functional Groups in Organic Chemistry
Acids and Bases
|Above a critical concentration, long, straight chain carboxylate salts, called soaps, derived from fatty acids, form a colloidal dispersion of spherical aggregates in water with the hydrophilic carboxylate groups on the outside and the lipophilic hydrocarbon chains toward the interior.|
If you have kids, be sure to tell them to mix the fatty acid salt with water and form a colloidal dispersion of spherical aggregates on their hands before dinner!
Soaps are formed by reacting a triglyceride with a strong Arrhenius base (hydroxide donor) to form carboxylate salts.
