Remove Tarnish from Silver

When silver tarnishes, it combines with sulfur and forms silver sulfide. Silver sulfide is black. When a thin coating of silver sulfide forms on the surface of silver, it darkens the silver.

Fundamental aspects of thiosulfate leaching of silver

The leaching of silver sulfide by cupric-ammonia thiosulfate can occur either by the substitution of cupric or cuprous for silver. The cupric catalyzed reaction is favored due to a thermodynamic barrier to the cuprous reaction. Rotating disk experiments demonstrate that cupric-ammonia leaching is under mixed chemical/diffusion control.
