i thought it would be elemental because right now i have amalgam tablets (3) which are silver and mercury mixed so i will be mixing that with HCl and producing AgCl and HgCl (and maybe HgNO3???) i will then dry this and get just those two salts then ill add water and the Hg ones will dissolve, ill filter this through a filter paper(thats good right?) and then ill dry both individually so ill have separated the mercury and silver salts
asides from what the colleagues already mentioned:
you won' t get nitrates if you don't use nitric acid additionally.
however, using conc. nitric acid / hydrochloric acid as a mix ( which, if memory serves, is required
to "break" the Hg-Ag-and then some - alloy , else, with pure HCl, next to nothing will happen) you will have nitroxides as side products, which are voilatile from the solution, and deadly poisenous. definitively
not something you wish to do without proper precautions ! this might quickly become suicidal!
and, having noted your other thread: Ag goes at US-$ 22,62 / oz.tr. these days
calculate like 25% by weight, typical, of silver in this dental alloy
calculate your costs , incl. further mercury salt modification / disposal
is this really worth your time?
