19. Which of the following is true? A. Water molecules that surround a less polar molecule in solution are immobile and ordered. B. Salt bridges are often found on the surface of proteins where they are stabilized by water. C. Micelles are stabilized in water by interactions of nonpolar molecules with each other. D. Hydrophobic interactions are sometimes called "bonds", because each one is as strong as a covalent bond. E. Both A and C 20. Which of the following is true? A. Since the pKa of acetic acid is 4.8, it can be used to prepare a buffer to maintain physiological pH. B. The buffering capacity of a weak acid and its conjugate base is strongest when the pH = pka.
