Thoughts on Ionic Substances
a Found Poem, by Christian Rock

If the salt contains
a cation that reacts
         With water
to produce hydronium ions
and an anion that does not react
          With water,
We expect the pH to be
          acidic.
Such is the case
When the cation is a
         conjugate acid
of a weak base
or a small cation
with a charge of
         2+ or greater.
Examples:
    NH4NO3,
       AlCl3,
           Fe(NO3)3


Kudos to anyone who can tell me what this is.
