Use this data to rank the following solutions in order of
increasing pH. In other words, select a '1'next to the solution
that will have the lowest pH, a '2' next to the solution that will
have the next lowest pH, and so on.

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−
The...

Unlike strong acids and bases that ionize completely in
solution, weak acids or bases partially ionize. The tendency of a
weak acid or base to ionize can be quantified in several ways
including
Ka or Kb,
pKa or pKb,
and percent ionization*.
*This assumes that species of equal concentrations are being
compared as percent ionization is affected by concentration.
