• The Chemistry of Photography

    the developer donate electrons to the silver halide grains. The electrons enter the conduction band of the compound and reduce more ionic silver to atomic silver. This occurs more rapidly and more completely in grains where photons already initiated this process. This is how the development is chemically accelerated at places in the photo that

    What is Oxidized Silver? A piece of blackened or oxidized silver is true sterling silver, but it's surface has been intentionally darkened through by introducing it to a chemical process. This patina, a surface color that occurs when the silver is introduced to sulfides, is a sped up version of the natural tarnishing process. A layer of silver sulfide forms on the exterior of the metal ...

  • Removing Tarnish from Silver – Compound Interest

     · Silver tarnishes in air to form a black coating of silver sulphide, which has the formula Ag 2 S. The chemical equation for the formation of silver tarnish following reaction with hydrogen sulphide (H 2 S) is as follows:. 2 Ag (s) + H 2 S (g) → Ag 2 S (s) + H 2(g). There's speculation that, in the present day, tarnishing of silver actually occurs more quickly due to the increased amounts ...

  • Silver, Chemical Element

    Chemical properties Silver is a very inactive metal. It does not react with oxygen in the air under normal circumstances. It does react slowly with sulfur compounds in the air, however. The product of this reaction is silver sulfide (Ag 2 S), a black compound. The tarnish that develops over time on silverware and other silverplated objects is silver sulfide.
