Question

Suppose a chloride ion and a sodium ion are separated by a center–center
distance of 5 Å. Is the interaction energy (the energy required to pull them
infinitely far apart) predicted to be larger if the medium between them is
water, or if it is n-pentane? (as shown)
If Ca2+, Na+, and F- each have ionic radii ~1.16. Which ionic bond is stronger: Ca-F or Na-F?
If Ca2+ is often bound on the surface of a protein by carboxylic acid functional groups. If the pKa of a particular -COOH group is 4.2, would
you predict Ca2+ to be most tightly bound at pH 8, pH 4.2, or pH 3? Explain your answer.
