Silver spoon to produce silver ions in water

(1/2) > >>

Rgmk:
I want to buy silver spoon to put it in the water to produce silver ions in it. What purity of the silver have to be used?
There are many spoons in the Internet that have black residue. Can I buy this spoon? Do I need to remove black residue before I start using it?
It is better to buy new spoon from the shop or it is no difference between new spoon from shop and old spoon from the Internet?
Sterling Silver is 925 it means that 75 is another admixtures. Does old silver has the same admixtures as the new one?

Corribus:
Metallic silver tarnishes due to presence of sulfides (e.g., H2S) in the atmosphere. This results in a surface layer of silver sulfide, which appears brown to black depending on the extent of tarnish. Tarnish will dissolve in acidic solution as well, so really it should not matter if the spoon is tarnished, but it is easy enough to polish away with commercially available silver cloth. Often you can do this dry - rubbing action alone can remove the surface tarnish leaving metallic silver beneath.

Silver salts have variable solubility in water, so depending on what you use to dissolve your silver, you may find various precipitates.

Silverware and other silver items should be stamped with the exact alloy designation, so you should be able to look up the purity using online resources.

Rgmk:
Ok. It means that if I buy spoon with surface tarnish and remove it I can use it to put to water and produce Ag ions. Tarnishing surface is not harmful to health? Even if some of it remains on spoon and I will put spoon in to water?

What is the purpose of it. To put a silverspoon in water will not produce much silverions, because Silber is a noble Element. The Tarnish is no problem, because if you er with a Silber Spion you get everytime it in your mouth.
