  2. Sodium chloride - Wikipedia

    en.wikipedia.org/wiki/Sodium_chloride

    Sodium chloride / ˌ s oʊ d i ə m ˈ k l ɔːr aɪ d /, [8] commonly known as edible salt, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chlorine ions. It is transparent or translucent, brittle, hygroscopic , and occurs as the mineral halite .

  3. Sodium fusion test - Wikipedia

    en.wikipedia.org/wiki/Sodium_fusion_test

    The sodium fusion extract is made alkaline by adding NaOH. To this mixture, freshly prepared FeSO 4 solution is added and boiled for sometimes and then cooled. A few drops of FeCl 3 are added and Prussian blue (bluish green) color forms due to formation of ferric ferrocyanide along with NaCl. This shows the presence of nitrogen in the organic ...

  4. Sodium compounds - Wikipedia

    en.wikipedia.org/wiki/Sodium_compounds

    The most important sodium compounds are table salt (NaCl), soda ash (Na 2 CO 3), baking soda (NaHCO 3), caustic soda (NaOH), sodium nitrate (NaNO 3), di- and tri-sodium phosphates, sodium thiosulfate (Na 2 S 2 O 3 ·5H 2 O), and borax (Na 2 B 4 O 7 ·10H 2 O). [7] In compounds, sodium is usually ionically bonded to water and anions and is ...

    A base and an acid anhydride, e.g., 2 NaOH + Cl 2 O → 2 NaClO + H 2 O; An acid and a base anhydride, e.g., 2 HNO 3 + Na 2 O → 2 NaNO 3 + H 2 O; In the salt metathesis reaction where two different salts are mixed in water, their ions recombine, and the new salt is insoluble and precipitates. For example:

  6. Acid–base reaction - Wikipedia

    en.wikipedia.org/wiki/Acid–base_reaction

    In chemistry, an acid–base reaction is a chemical reaction that occurs between an acid and a base.It can be used to determine pH via titration.Several theoretical frameworks provide alternative conceptions of the reaction mechanisms and their application in solving related problems; these are called the acid–base theories, for example, Brønsted–Lowry acid–base theory.

  7. Chloralkali process - Wikipedia

    en.wikipedia.org/wiki/Chloralkali_process

    This depends on factors such as solution temperature, the amount of time the Cl 2 molecule is in contact with the solution, and concentration of NaOH. Likewise, as hypochlorite increases in concentration, chlorates are produced from them: 3 NaClO → NaClO 3 + 2 NaCl. This reaction is accelerated at temperatures above about 60 °C.

  8. Finkelstein reaction - Wikipedia

    en.wikipedia.org/wiki/Finkelstein_reaction

    The classic Finkelstein reaction entails the conversion of an alkyl chloride or an alkyl bromide to an alkyl iodide by treatment with a solution of sodium iodide in acetone. Sodium iodide is soluble in acetone while sodium chloride and sodium bromide are not; [ 3 ] therefore, the reaction is driven toward products by mass action due to the ...

  9. Neutralization (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Neutralization_(chemistry)

    The concept of neutralization is not limited to reactions in solution. For example, the reaction of limestone with acid such as sulfuric acid is also a neutralization reaction. [Ca,Mg]CO 3 (s) + H 2 SO 4 (aq) → (Ca 2+, Mg 2+)(aq) + SO 2− 4 (aq) + CO 2 (g) + H 2 O. Such reactions are important in soil chemistry.
