Expert Solution
HF(aq) + H2O(l) <---> H3O+(aq) + F-(aq)
HNO2(aq) + H2O(l) <---> H3O+(aq) +NO2-(aq)
HCN(aq) + H2O(l) <---> H3O+(aq) + CN-(aq)
CH3COOH(aq) + H2O(l) <---> H3O+(aq) + CH3COO-(aq)
The triprotic acid:
H3PO4(aq) + H2O(l) <--> H3O+(aq) + H2PO4-(aq)
H2PO4-(aq) + H2O(l) <--> H3O+(aq) + HPO4-2(aq)
HPO4-2(aq) + H2O(l) <--> H3O+(aq) + PO4-3(aq)
Overall
H3PO4(aq) + H2O(l) <--> 3H3O+(aq) + PO4-3(aq)

Unlike strong acids and bases that ionize completely in
solution, weak acids or bases partially ionize. The tendency to
ionize (i.e., the ionic strength) of a weak acid or base can be
quantified in several ways including
Ka or Kb,
pKa or pKb,
and percent ionization.
Part A
Pyridine is a weak base that is used in the manufacture of
pesticides and plastic resins. It is also a component of cigarette
smoke. Pyridine ionizes in water as follows:
C5H5N+H2O⇌C5H5NH++OH−

*This assumes that species of equal concentrations are being
compared as percent ionization is affected by concentration.

When a strong acid is neutralized by a weak base is the
neutralization complete? Write the neutralization reaction for
HClO4 and NH3. What is the value of Kn (equilibrium constant for
neutralization)? (Kb(NH3)=1.810‒5) If stoichiometric amounts of
acid and base are reacted will the resulting solution be acidic,
basic or neutral?

b. Weak acids dissociate completely if the pH is raised
c. Weak acids have a pKa
d. Weak acids can serve as buffers
E. Weak acids dissociate completely at an pH
