Seriously..............? This is like putting the cart before the horse............ Why not order some tilt switches from China via eBay.

Because i can get a lot of mercury iodine for fairly cheap (much cheaper than switches). Also one switch contain only very little mercury and i would
need to break a lot of them to get usefull amount of mercury. fusso - 28-2-2019 at 05:30
Have you calculated the price per mol of Hg from both sources? Is the HgI2 really cheaper than switches in $/mol?Ubya - 28-2-2019 at 10:00
mercury (II) iodide is barely soluble in water, but if you add enough KI or NaI you can solubilize it as the tetraiodomercurate ion, and maybe (need
fact checking) with electrolysis you can get mercury metal and elemental iodineDraconicAcid - 28-2-2019 at 11:11

Once you've got it in solution, it shouldn't be hard to reduce it to the metal with aluminum or another metal.
Part of me wants to make a joke about mixing the solid with aluminum powder and doing a thermite-like reduction, but the sensible part of me is too
worried that someone might try it.unionised - 28-2-2019 at 13:37
I'm fairly sure that an alkaline solution of mercury iodide in KI can be reduced by formaldehyde or acetaldehyde.
That avoids the addition of any other metals.Chem Science - 1-3-2019 at 05:49
Try adding some nitric acid, these will make iodine and mercury nitrate. Then the mercury nitrate can be converted to mercury by decomposition
Hg(NO3)2 = Hg + 2NO2 + O2
I did these for lead iodide and it worked ! Ubya - 1-3-2019 at 09:19

i would just displace the mercury ion with copper metal, no need to work with mercury vapour and copious amounts of NO2fusso - 1-3-2019 at 09:41

I'd use Fe instead of Cu as Fe is insoluble in Hg if I want to use displacement.Abromination - 1-3-2019 at 21:46
No offense OP, but if you need to ask questions like this then perhaps working with toxic mercury salts is not the best of ideas. Please consider
finding a different source. If you are a confident chemist, I suppose go ahead but if you doubt your capability, don't.Lion850 - 25-11-2019 at 22:17
Hi mech252 did you manage to extract mercury from your iodide? Corrosive Joeseph - 25-11-2019 at 22:28
The OP was last seen one month after the first post.....He was only here for a total of 3 posts over a period of 4 weeks. His email address is in his
profile but I don't believe he was succesful.
