Dear Sir,
Please let me know with the reverse proportion of aqua regia, it will digest both silver and gold bid obtained from fire assay method.
Because of HCL, silver will precipitate. So please suggest me suitable combination to digest the bid.
Thanks in advance.

Is there any particular reason why less silver will inhibit the dissolution? Or is it just based on an experiment that the best ratio is 3:1?
