Chapter 2
The Chemical Foundation of Life: Weak Interactions in an Aqueous Environment

1. a. Equation 2.3 predicts that the interaction energy between the
ions will be greater in the lower dielectric medium; thus, the
attraction between the and will be greater in pentane.
b. Since the length of the ionic bonds is Å in each case (i.e.,
the value of r is the same for Ca-F and Na-F), Equation 2.3
predicts that the interaction energy between the ion will be
greater as the values of q increase; thus, the attraction between
the and will be greater than the attraction
between the and
c. Ca will be bound more tightly by a COOH group that is fully
2

deprotonated. At pH  3 the COOH form will predominate. At
pH  4.2 the COOH and COO forms will be in equal
concentration. At pH 8 the COO will predominate; thus, expect
greatest Ca2 binding at pH  8.
2. In the upper pair NH is the donor and O is the acceptor. This is the
more likely interaction. In the lower pair, the one NH is the donor
and the other N is the acceptor.




3. The curve shown in the question describes the situation where the
water dipoles are parallel and side by side. Assuming the
antiparallel dipoles are also side by side (rather than head to tail),
the curve would be the mirror image reflected across the Energy 
0 line on the y-axis.
4. a. HCl is a strong acid; thus, [HCl]  [H] and pH  log[H] 
log[0.35]  0.456
b. Acetic acid is a weak acid with Ka  1.74  105; thus, use ICE
table to solve this problem:
