Well the answer is....Nothing! I got a cracked tube but thats about it, i honestly thought hot Nickel and iodine would react. Hmmm
I cant make any Iodine monochloride at the moment, i bet it would react with that  .

Maybe if you use powdered metal, the reaction works better.
Nickel has a tendency to form a thin protective layer which prevents further reaction. For this reason it is even possible to store fluorine in a
nickel container. The formed layer of NiF2 protects the underlying metal. This almost certainly also is true for NiCl2 and NiBr2. Maybe it also is the
case for NiI2, but I can imagine that this halide is not sufficiently stable and simply decomposes on heating. I have no personal experience with that
though.

I closed the tube with a heavy glass thimble on top, i had a tiny amount of water in the tube. Looking at it afterwards something did react a little
and I also saw a few red drips.
Some of the powder is alot finer than the rest, i will separate this out. I could do with a decent ball mill! That way I can keep the bulk in larger
flakes and the mill it as I need it,
I am also storing it in a pretty airtight container. I will try again later

You might also find that it works better in a solvent that will dissolve iodine (I've reacted zinc with iodine using methanol as the solvent, and have
vague memories of trying it with iron and possibly nickel).
Please remember: "Filtrate" is not a verb.
Write up your lab reports the way your instructor wants them, not the way your ex-instructor wants them.

That I can go do now! I have Methanol handy. A couple of coffee things i want to do as well. Then i got to clear the lab up!
Really i should get it sorted first, i got the inspection coming up. This is where a dishwasher for the lab would be cool.
Not good! Maybe its way too cold in the lab, going to have a clean and tidy and reflux this.
