  2. 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 some time 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 ...

  3. 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 .

  4. Salt (chemistry) - Wikipedia

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

    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:

  5. Neutralization (chemistry) - Wikipedia

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

    For example, sodium hydroxide, NaOH, is a strong base. NaOH(aq) → Na + (aq) + OH − (aq) Therefore, when a strong acid reacts with a strong base the neutralization reaction can be written as H + + OH − → H 2 O. For example, in the reaction between hydrochloric acid and sodium hydroxide the sodium and chloride ions, Na + and Cl − take ...

  6. Sodium chlorate - Wikipedia

    en.wikipedia.org/wiki/Sodium_chlorate

    Sodium chlorate can be mixed with sucrose sugar to make a highly energetic fuel, similar to that of gunpowder, that burns in airtight spaces. This is the reaction: This is the reaction: 8 NaClO 3 + C 12 H 22 O 11 → 8 NaCl + 12 CO 2 + 11 H 2 O

  7. Finkelstein reaction - Wikipedia

    en.wikipedia.org/wiki/Finkelstein_reaction

    Vinyl, aryl and tertiary alkyl halides are unreactive; as a result, the reaction of NaI in acetone can be used as a qualitative test to determine which of the aforementioned classes an unknown alkyl halide belongs to, with the exception of alkyl iodides, as they yield the same product upon substitution.

  8. List of reagents - Wikipedia

    en.wikipedia.org/wiki/List_of_reagents

    Reagents are "substances or compounds that are added to a system in order to bring about a chemical reaction or are added to see if a reaction occurs." [1] Some reagents are just a single element. However, most processes require reagents made of chemical compounds. Some of the most common ones used widely for specific reactive functions are ...

  9. Qualitative inorganic analysis - Wikipedia

    en.wikipedia.org/wiki/Qualitative_inorganic_analysis

    The solution is then treated with various reagents to test for reactions characteristic of certain ions, which may cause color change, precipitation and other visible changes. [ 1 ] [ 2 ] Qualitative inorganic analysis is that branch or method of analytical chemistry which seeks to establish the elemental composition of inorganic compounds ...
