  2. Silver nitrate - Wikipedia

    en.wikipedia.org/wiki/Silver_nitrate

    A typical reaction with silver nitrate is to suspend a rod of copper in a solution of silver nitrate and leave it for a few hours. The silver nitrate reacts with copper to form hairlike crystals of silver metal and a blue solution of copper nitrate: 2 AgNO 3 + Cu → Cu(NO 3) 2 + 2 Ag. Silver nitrate decomposes when heated:

  3. Nitrate test - Wikipedia

    en.wikipedia.org/wiki/Nitrate_test

    Nitrate Test by using Brown Ring Test. A common nitrate test, known as the brown ring test [2] can be performed by adding iron(II) sulfate to a solution of a nitrate, then slowly adding concentrated sulfuric acid such that the acid forms a layer below the aqueous solution. A brown ring will form at the junction of the two layers, indicating the ...

  4. Tollens' reagent - Wikipedia

    en.wikipedia.org/wiki/Tollens'_reagent

    The diamine silver(I) complex in the mixture is an oxidizing agent and is the essential reactant in Tollens' reagent. The test is generally carried out in a test tube in a warm water bath. In a positive test, the diamine silver(I) complex oxidizes the aldehyde to a carboxylate ion and in the process is reduced to elemental silver and aqueous ...

  5. Argentometry - Wikipedia

    en.wikipedia.org/wiki/Argentometry

    In analytical chemistry, argentometry is a type of titration involving the silver(I) ion. Typically, it is used to determine the amount of chloride present in a sample. The sample solution is titrated against a solution of silver nitrate of known concentration. Chloride ions react with silver(I) ions to give the insoluble silver chloride:

  6. Silver hyponitrite - Wikipedia

    en.wikipedia.org/wiki/Silver_hyponitrite

    The salt can be precipitated from a solution of sodium hyponitrite in water by the addition of silver nitrate: [2] Na 2 N 2 O 2 + 2 AgNO 3 → Ag 2 N 2 O 2 + 2 NaNO 3. Excess silver nitrate yields a brown or black precipitate. [1] [2] Silver hyponitrite can also be prepared by reacting silver nitrate with sodium amalgam. [5]

  7. Argentation chromatography - Wikipedia

    en.wikipedia.org/wiki/Argentation_chromatography

    Silver ions form alkene complexes. The binding is reversible, but sufficient to impede the elution of the alkene-containing analytes. Structure of the complex of silver nitrate and trans-cyclooctene. Color code: red = O, bright blue = N, dark blue = Ag, gray = C, white = H. [3]

  8. Warthin–Starry stain - Wikipedia

    en.wikipedia.org/wiki/Warthin–Starry_stain

    The Warthin–Starry stain (WS) is a silver nitrate-based staining method (a silver stain) used in histology. It was first introduced in 1920 by American pathologists Aldred Scott Warthin (1866–1931) and Allen Chronister Starry (1890–1973), for the detection of spirochetes .

    en.wikipedia.org/wiki/Wikipedia:Silver_nitrate

    Silver nitrate is a salt of silver that is sometimes used by dentists as a caustic material to cauterize mouth sores, and has in the past been used by physicians for treating wounds. It may be an appropriate material to salt the earth after burying a monster that has been killed with silver bullets .
