That's my problem Caplock! He kinda jumps around in what to do and is quick to "estimate" alot of stuff... All 3 of his videos are like that. And the other video just shows how it's done but no measurements at all.
I looked on the man's website
http://augmentinforce.50webs.com/ and do not quickly see any exact information, but am looking.
I'm hoping someone can give a better link or instructions.
Iodine crystals are used in a couple of the experiments in the book. When I wrote
those sections, iodine was freely available, but the DEA recently moved iodine to List I,
which means it now requires completing paperwork and showing ID to purchase iodine.
Fortunately, there's a very easy way around this problem. You can isolate elemental
iodine from potassium iodide, which is included in one of the chemical kits. To do so,
take the following steps:
1. Weigh out 2.0 g of potassium iodide and transfer it to a test tube.
2. Add about 1.5 mL of distilled water to the test tube and swirl to dissolve
the potassium iodide.
3. Add 1.5 mL of concentrated hydrochloric acid (or about 1.8 mL
of hardware store muriatic acid) to the test tube and swirl to mix
the solutions.
4. Add about 10 mL of drugstore 3% hydrogen peroxide. The solution
immediately turns dark brown as the iodide ions are oxidized to elemental
iodine, which precipitates out.
5. Swirl the test tube to suspend the iodine and pour the liquid through a
funnel with a folded piece of filter paper to capture the iodine crystals.
6. Rinse the iodine crystals on the filter paper several times with a few mL
of distilled water. The rinse solution appears brown from dissolved iodine,
but iodine is not very soluble in water, so you're not losing much of your
yield.
7. Spread out the filter paper on a watch glass or saucer and allow the
crystals to dry thoroughly. Iodine gradually sublimates (passes directly
from solid to gaseous form) at room temperature, so don't leave the
crystals exposed to air any longer than necessary to dry them.
8. Once the crystals are dry, transfer them to a sealed storage bottle or
vial.
These quantities produce a gram or so of iodine, which is sufficient for the
experiments that require it. If you need more iodine, simply increase all
quantities proportionately.
