Hey Everybody,
Got 1 gal. solution of ...
7% iodine
80% ipa
13% h2o
From the notes I've read here...to make enough HgI2 for a 1x MM alhg, one plops .3-.5g Hg (l) into a 30ml solution of 2% iodine tincture...shake and bake. Now, my questions are...
1) I'm sure I should use 99% ipa to dillute the solution down to 2%, no? Any other suggestions...MeOH or EtOH?
2) After the solution is dilluted down to 2% iodine, its still going to be ~3-4% water. Is this going to be a problem
adding this extra h2o to a 1x MM al-hg rxn.?
Cheers...a

My version of this product contains no added water, just 99% isopropanol. I see no reason to perform any dilution: your solution is of greater purity than the 2% tincture, so why adulterate it? The formulaic procedure you are following, is adapted to the availability of the less desirable merchandise. Plop your Hg in, see it happen.

Thanks for the advice halfapint...I was intending to dillute the 7% down to make it fit rxn. guidelines but I was also concerned about getting the h2o % down a bit as well...any comments?
thanks...a
