Hello pinholers,

Does anyone have some solid iodine that I can use next week? We need
it for a lab, and didn't deal with ordering it soon enough. I only
need 1 or 2 grams.

(I can pay you for it.)

Thanks,
Geoff

Hi Geoff,
if you have the following ingredients & follow the instructions listed, you
can make Iodine.
Weigh 0.54 gm Potassium IODATE
          10.0 gm Potassium IODIDE
Place contents in 1000 ml Erlynmeyer
Add ~300 ml of Water
Add 3 M H2SO4 - carefully
Mix and top off to 1000 ml with water and you now have 1000 mls of Iodine

Hope this helps
