I was hoping there was a method for separating the menials in non lead solder. The main metals in solder are Tin, coper indium and silver. The solder
I have is Tin and silver. I guess That if I wanted tin I could just use it as is but can I remove the silver? Maybe adding nitric acid to make tin
oxide and silver nitrate?

Then you'd want to remove the silver by adding copper to the silver nitrate to get silver metal. Or you could add salt to precipitate the silver as
AgCl.

awesome thanks

I am going to try dissolving the alloy in HCl and whats left over is silver.

There will also be copper left. It may be tough to see because it a very fine precipitate.

how well does it act as a electrode

As far as I remember, dissolving solder in nitric acid, produces hydrated SnO, not Sn2+. This is precipitated as a white to yellowish rather
voluminous precipitate, called tin butter (SnO.xH2O). I used this procedure to separate tin and lead from a piece Sn/Pb solder wire, the lead
remaining in solution.
I imagine the same to happen with alloys of tin and silver, the silver remaining in solution.

Cool, thank you for the info.
