When storing silver nitrate for disposal, it's best to find a container like the one it came in (i.e. glass reagent bottle). Remember that silver nitrate is corrosive, so don't use metal containers. The container should be stored in a cool, dry location and not exposed to sunlight.

AgNO 3 + NaCl = AgCl + NaNO 3 | Silver Nitrate + Sodium Chloride Reaction. When aqueous AgNO 3 and aqueous NaCl compounds are mixed together, there is a high chance of giving a white colour precipitate if initial silver nitrate and initial sodium chloride concentrations are considerably high. . That means, AgNO 3 and NaCl is a precipitation reac

It seems to me one could monitor the progress of this extraction by measuring the curpic nitrate in the electrolyte (the blue color intensity should go down) and the selectivity of the extraction by measuring the silver concentration in the cell using the Volhard titration ( which works really well).

Silver sulfate filters super nice and it holds up PbSO4/Au/SnO2.H2Ox nicely. Precipitating the AgCl 1. To the remaining silver solution which may contain base metal nitrates in large quantities (Zn, Cu, Pd, Ni, etc.) I would add HCl such that there is an excess in solution and the silver is thrown down entirely as flocculant AgCl.

4metals: How about to dissolve those silver bars in nitric acid and precipitate with common salt?.Lead chloride is soluble in hot water,silver chloride is not soluble so you can remove all the lead.This is the Karo syrup method just using hot distilled wter instead of tap water to rinse the white mud of chlorides.(Lead chloride seems like silver chloride).

The silver chloride is then washed with water until the washings are neutral. It is then reduced by zinc or iron. On a large scale a lead-lined box or vat serves for the reduction. The silver chloride is introduced, then the zinc required for the reduction added. Zn + 2AgCl = Zn Cl2 + 2Ag. At least 65 parts by weight of zinc to 287 of silver ...

The silver sent out to assay was melted and shotted. All of the feedstock for the refining process is sterling and we assay it with the Volhard titration as well. I prefer the sodium formate reduction of silver to a silver cell because we inquart karat into the starting alloy and produce a high purity gold residue as a side benefit.

TUTORIAL FOR NEWBIES: When a metal is "dissolved" in a solution, it is in "ionized" form (missing some its electrons). In the specific case of silver nitrate, the formula for the solution is AgNO 3, or Ag + + NO 3-.The solution contains silver ions of "plus 1" charge (they are one electron short of being silver atoms) and nitrate ions of "minus 1" charge.

Copper being more reactive than silver makes removing copper and leaving silver in solution very difficult. Consider: Adding a bar of copper cement your silver, now you are left with primarily a copper nitrate solution. Now that you have elemental silver you can put back into solution if that is what you wish, or refine it further or melt it...

Silver nitrate starts to break down to silver oxide at 250 C and is totally decomposed at 440 C. Silver oxide decomposes into silver and oxygen between 200 C and 300 C, so the nitrate should turn into silver quite easily. A byproduct will be the well known red cloud of NOx usually produced by nitric acid. Göran
