does silver rust?

Answer 1

in layman's language,yes it does. it gets a bluish-blackish coating by reacting with H2S from air after some time.

Answer 2

Does Silver Rust

Answer 3

Silver oxidizes (i.e. rusts) but at a much, much slower rate than iron. This is not to be confused with mere tarnishing. Rather than turning orange like iron, silver turns blue-black and eventually gets just as brittle as rusted iron.

Answer 4

Silver does not "rust." Rust as a common term is iron oxide. It is created when iron is in the presence of O2 and oxidizes. So no silver does not "Rust" because silver is not iron but under specific conditions silver can oxidize.

Answer 5

If you mean hydroxidation, especially hydroxidation that causes Ag hydroxides to flake and fall off as e.g. in iron, no.

If you mean oxydation changing the surface aspect, yes.

Ag becomes "tarnished", i.e. it combines with oxygen to form an oxide that has a grey-black opaque color. It's only a superficial layer, which eventually provides enough barrier to slow or stop further oxydation - if not continually removed.

One interesting aside is that silver oxydes are almost as conductive as pure silver, so the metal is a good option for plating electrical contacts that are supposed to last over time and not to lose conductivity.

Answer 6

In a way yes. When steel rusts it really oxidizing. Silver does oxidize but it doesnt happen as fast and is easily removed with a cleaner.

Answer 7

Silver, Ag, does not rust in the sense that it combines with air oxygen, O2, to form Ag2O. But silver does react very slowly with minute amounts of hydrogen sulfide in the air to form silver sulfide tarnish, Ag2S. The tarnish means that the silver is indeed "rusting away," and silver-plated objects will lose the silver entirely from over the base metal in a matter of decades.

Answer 9

We call oxidation of steel (iron) rust we call oxidation on silver tarnish.

Answer 10

In the sense that rust is oxydation, and tarnish is oxydation, yes. But it doesn't 'rust' away.

Answer 11

I am pretty sure silver, gold, and lead don't rust, there might be others.
