Medical uses of silver - Wikipedia

The medical uses of silver include its use in wound dressings, creams, and as an antibiotic coating on medical devices. Wound dressings containing silver sulfadiazine or silver nanomaterials may be used on external infections. The limited evidence available shows that silver coatings on endotracheal breathing tubes may reduce the incidence of ventilator-associated pneumonia.

Silver Recovery Methods

Metallic replacement is a process where elemental iron undergoes an oxidation-reduction reaction with the silver thiosulfate to produce ferrous ions and metallic silver. The exchange reaction is very rapid, but dependent on the contact of the silver-thiosulfate complex with the iron surface.

22-3-2013· 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.
