  2. Sodium nitrate - Wikipedia

    en.wikipedia.org/wiki/Sodium_nitrate

    Sodium nitrate is the chemical compound with the formula Na N O 3. This alkali metal nitrate salt is also known as Chile saltpeter (large deposits of which were historically mined in Chile) [4] [5] to distinguish it from ordinary saltpeter, potassium nitrate. The mineral form is also known as nitratine, nitratite or soda niter.

  3. Hummers' method - Wikipedia

    en.wikipedia.org/wiki/Hummers'_Method

    The basic chemical reaction involved in the Hummers' method is the oxidation of graphite, introducing molecules of oxygen to the pure carbon graphene. The reaction occurs between the graphene and the concentrated sulfuric acid with the potassium permanganate and sodium nitrate acting as catalysts.

  4. Nanochemistry - Wikipedia

    en.wikipedia.org/wiki/Nanochemistry

    Nanochemistry is an emerging sub-discipline of the chemical and material sciences that deals with the development of new methods for creating nanoscale materials. [1] The term "nanochemistry" was first used by Ozin in 1992 as 'the uses of chemical synthesis to reproducibly afford nanomaterials from the atom "up", contrary to the nanoengineering and nanophysics approach that operates from the ...

  5. Nitratine - Wikipedia

    en.wikipedia.org/wiki/Nitratine

    Nitratine was once an important source of nitrates for fertilizer and other chemical uses including fireworks.It has been known since 1845 from mineral deposits in the Confidence Hills, Southern Death Valley, California and the Atacama Desert, Chile.

  6. Sodium nitrite - Wikipedia

    en.wikipedia.org/wiki/Sodium_nitrite

    Sodium nitrite is an inorganic compound with the chemical formula Na N O 2. It is a white to slightly yellowish crystalline powder that is very soluble in water and is hygroscopic . From an industrial perspective, it is the most important nitrite salt.

  7. Alkali metal nitrate - Wikipedia

    en.wikipedia.org/wiki/Alkali_Metal_Nitrate

    Alkali metal nitrates are chemical compounds consisting of an alkali metal (lithium, sodium, potassium, rubidium and caesium) and the nitrate ion. Only two are of major commercial value, the sodium and potassium salts. [1] They are white, water-soluble salts with melting points ranging from 255 °C (LiNO 3) to 414 °C (CsNO

  8. Solubility chart - Wikipedia

    en.wikipedia.org/wiki/Solubility_chart

    The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

  9. Sodium nitride - Wikipedia

    en.wikipedia.org/wiki/Sodium_nitride

    Sodium nitride is the inorganic compound with the chemical formula Na 3 N. In contrast to lithium nitride and some other nitrides, sodium nitride is an extremely unstable alkali metal nitride. It can be generated by combining atomic beams of sodium and nitrogen deposited onto a low-temperature sapphire substrate. [1]
