How to purify silver from silver chloride
« on: January 22, 2012, 11:11:41 AM »
I have a sulfuric acid solution of silver sulfate + potassium dichromate + and pulled out the silver by adding salt, then I do the casting and filter that filtered getting a small bar of metal silver color but with some shares through white. That's right, it is silver that I have it?

Your reduction may not have been complete.  Silver chloride can be melted and forms a very durable ingot itself.  A solid block of silver chloride comes in useful too, as an electrode.  The best way to get the purest silver is to dissolve it in nitric acid, and replace it from solution with copper wire, the silver dendritic crystals are pretty, and can be easily scrapped off and melted.
Hey, I'm not judging.  I just like to shoot straight.  I'm a man of science.

I then just dissolve in nitric acid and put a copper wire in and what retitar be glued and merge? It will be difficult to remove silver from the copper wire?

The little bar that I got is fragile, can break with his hand, he has parts silver and white parts transparent
