Well, I'm no chemist, but I do have a couple of thoughts.  

1.  NaOH is a strong base, and if anything, your pH would *rise* (not what
you were after); however, those dropper bottles are pretty small, and I
can't imagine the concentration of NaOH is super high; otherwise you'd have
to have all sorts of warnings on the label (anybody know the [NaOH] of
these solns?).  With a large amount of water, and a few drops of the stuff,
my GUESS is that not much would happen w/ the pH.  I woudn't make a
practice of gettting the stuff on you, though.

2.  The mercuric iodide is of more concern.  It is registered as a poison,
and apparently has some fairly nasty effects.  Again, don't know the
concentration, and you have further diluted it, but I'd still be very

Just for general edification, there is a good web site sponsored by
Interactive Learning Paradigms, Inc. that has all kinds of links for MSDSs.
 The MSDS is good place to start when you have questions about chemicals.
