  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. 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 ...

  4. 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 ...

  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 compounds - Wikipedia

    en.wikipedia.org/wiki/Silver_compounds

    Some silver oxide powder.. Silver is a relatively unreactive metal, although it can form several compounds. The common oxidation states of silver are (in order of commonness): +1 (the most stable state; for example, silver nitrate, AgNO 3); +2 (highly oxidising; for example, silver(II) fluoride, AgF 2); and even very rarely +3 (extreme oxidising; for example, potassium tetrafluoroargentate(III ...

  7. Silver - Wikipedia

    en.wikipedia.org/wiki/Silver

    Silver is a naturally occurring element. It is found in the environment combined with other elements such as sulfide, chloride, and nitrate. Pure silver is “silver” colored, but silver nitrate and silver chloride are powdery white and silver sulfide and silver oxide are dark-gray to black.

  8. 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]

  9. Silver nitrite - Wikipedia

    en.wikipedia.org/wiki/Silver_nitrite

    Silver nitrite is produced from the reaction between silver nitrate and an alkali nitrite, such as sodium nitrite. [3] Silver nitrite is much less soluble in water than silver nitrate, and a solution of silver nitrate will readily precipitate silver nitrite upon addition of sodium nitrite: AgNO 3 (aq) + NaNO 2 (s) → NaNO 3 (aq) + AgNO 2 ...
