Concept explainers

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.

What is the purpose of the ion exchange resin? A. The ion exchange resin removes Ca2+ and Mg2+ out of hard water to make it soft. B. The ion exchange resin takes out Ca2+ and gets rid of Na which makes the hard water softer. C. The ion exchange resin replaces the Ca2+ and Mg2+ in hard water with Na+ ions so the cleansing properties of the soap are retained. D. The ion exchange resin increases the amount of foam because it made the solution softer instead of hard water and you get more foam with soft water.
