When I make it up I shake the dry Iodine and dry Potassium Iodide together
vigorously, then add the distilled water slowly while stirring with a stir
bar until dissolved. It does take a while to fully dissolve.
Good luck,

Dear Histos,

I am trying to make a Gram's Iodine solution (1g iodine, 2g potassium
iodide, 100ml distilled water to start)and I can't get the iodine to go into
solution.  If I use a stir bar the iodine is attracted to the magnet and
doesn't come off.  I've also tried heat and that doesn't seem to work
 All the text books I've looked at say shake until dissolved.  Tried that,
the iodine just sits in the bottom of the beaker and nothing.

I don't remember having this problem before in school.  All suggestions are
welcome.  Thanks in advance.
