  2. Nitrate - Wikipedia

    en.wikipedia.org/wiki/Nitrate

    Nitrate is a polyatomic ion with the chemical formula NO−3. Salts containing this ion are called nitrates. Nitrates are common components of fertilizers and explosives. [ 1 ] Almost all inorganic nitrates are soluble in water. An example of an insoluble nitrate is bismuth oxynitrate.

  3. Nitrate test - Wikipedia

    en.wikipedia.org/wiki/Nitrate_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 presence of the nitrate ion. [ 3 ]

  4. Potassium nitrate - Wikipedia

    en.wikipedia.org/wiki/Potassium_nitrate

    Potassium nitrate is a chemical compound with a sharp, salty, bitter taste and the chemical formula K N O 3. It is an ionic salt of potassium ions K + and nitrate ions NO 3 −, and is therefore an alkali metal nitrate. It occurs in nature as a mineral, niter (or nitre outside the US). [5] It is a source of nitrogen, and nitrogen was named ...

  5. Ammonium nitrate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_nitrate

    Ammonium nitrate is a chemical compound with the formula NH4NO3. It is a white crystalline salt consisting of ions of ammonium and nitrate. It is highly soluble in water and hygroscopic as a solid, although it does not form hydrates. It is predominantly used in agriculture as a high-nitrogen fertilizer.

  6. Nitrite - Wikipedia

    en.wikipedia.org/wiki/Nitrite

    The nitrite ion has the chemical formula NO − 2.Nitrite (mostly sodium nitrite) is widely used throughout chemical and pharmaceutical industries. [1] The nitrite anion is a pervasive intermediate in the nitrogen cycle in nature.

  7. Zinc nitrate - Wikipedia

    en.wikipedia.org/wiki/Zinc_nitrate

    Zinc nitrate is an inorganic chemical compound ... and, thus, this reaction may be better written as the reaction of the aquated ion with hydroxide through ...

  8. Ion - Wikipedia

    en.wikipedia.org/wiki/Ion

    An ion (/ ˈaɪ.ɒn, - ən /) [ 1 ] is an atom or molecule with a net electrical charge. The charge of an electron is considered to be negative by convention and this charge is equal and opposite to the charge of a proton, which is considered to be positive by convention. The net charge of an ion is not zero because its total number of ...

  9. Silver nitrate - Wikipedia

    en.wikipedia.org/wiki/Silver_nitrate

    Silver nitrate is the least expensive salt of silver; it offers several other advantages as well. It is non- hygroscopic, in contrast to silver fluoroborate and silver perchlorate. In addition, it is relatively stable to light, and it dissolves in numerous solvents, including water.
