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.

Why is potassium hydrogen phthalate (KHP) used to standardize the NaOH solution instead of measuring out a known mass of solid NaOH to be dissolved in water? KHP is an acid and will neutralize some of the NaOH to use later. O There is no reason, NaOH solutions can be used without standardization. O Solid NaOH is hygroscopic and will absorb water, making it virtually impossible to determine a true initial mass and therefore changing the concentration of the solution. Solid NaOH evaporates therefore its concentration can never be known.
