how many metals can amalgam on mercury ?
Click For Summary
Discussion Overview
The discussion centers on the solubility of various metals in mercury and the formation of amalgams, particularly focusing on the metals gold (Au) and silver (Ag). The context includes both theoretical and practical aspects of metal amalgamation with mercury.
Discussion Character
- Exploratory, Technical explanation, Experimental/applied
Main Points Raised
- One participant inquires about the number of metals that can amalgamate with mercury.
- Another participant suggests that all metals are to some extent soluble in mercury.
- A participant mentions depositing mercury on a graphite electrode and successfully amalgamating gold and silver.
- It is noted that both silver and gold are well soluble in mercury, although high concentrations may pose challenges.
- A participant indicates they are working with sub-ppm concentrations of metals in mercury.
- Another participant reassures that working with sub-ppm concentrations is likely safe.
Areas of Agreement / Disagreement
Participants generally agree that gold and silver can amalgamate with mercury, but there is no consensus on the extent of solubility for all metals or the implications of working with varying concentrations.
Contextual Notes
The discussion does not clarify the specific conditions under which different metals may amalgamate or the limitations of solubility in practical applications.

Please elaborate. As far as I remember all metals are to some extent soluble in Hg.

thanks.
I deposite a layer of mercury on PG graphite electrode. then amalgam Au and Ag in it.

Should be no problem, both Ag and Au are well soluble in Hg. Unless you plan to do something that requires quite high concentrations.

I work on sub (ppm) concentration.
however thanks for your Attention.
best regards.
