  3. Ammonium - Wikipedia

    en.wikipedia.org/wiki/Ammonium

    The hydrogen atoms in the ammonium ion can be substituted with an alkyl group or some other organic group to form a substituted ammonium ion (IUPAC nomenclature: aminium ion). Depending on the number of organic groups, the ammonium cation is called a primary, secondary, tertiary, or quaternary. Except the quaternary ammonium cations, the ...

  4. Ammonia - Wikipedia

    en.wikipedia.org/wiki/Ammonia

    Like water, liquid ammonia undergoes molecular autoionisation to form its acid and base conjugates: 2 NH 3 ⇌ NH + 4 + NH − 2. Ammonia often functions as a weak base, so it has some buffering ability. Shifts in pH will cause more or fewer ammonium cations (NH + 4) and amide anions (NH − 2) to be present in solution. At standard pressure ...

    Boil a solution of 20 g ammonium molybdate and 5 g of sodium thiosulfate in a liter of water, immerse the objects, rinse, dry, wax or lacquer after the development of color. [31] Lustre colours. Use a solution of 280 g of sodium thiosulphate, 25 g of cupric acetate and 30 g of citric acid. It can be used on copper and its alloys, silver, nickel ...

  6. Metal ammine complex - Wikipedia

    en.wikipedia.org/wiki/Metal_ammine_complex

    An ammine ligand bound to a metal ion is markedly more acidic than a free ammonia molecule, although deprotonation in aqueous solution is still rare. One example is the reaction of mercury(II) chloride with ammonia (Calomel reaction) where the resulting mercuric amidochloride is highly insoluble. HgCl 2 + 2 NH 3 → HgCl(NH 2) + [NH 4]Cl

  7. Ammonium perrhenate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_perrhenate

    Ammonium perrhenate (APR) is the ammonium salt of perrhenic acid, NH 4 ReO 4. It is the most common form in which rhenium is traded. It is a white salt; soluble in ethanol and water, and mildly soluble in NH 4 Cl. [ 2 ]

  8. Ammonium alum - Wikipedia

    en.wikipedia.org/wiki/Ammonium_alum

    Ammonium aluminium sulfate, also known as ammonium alum or just alum (though there are many different substances also called "alum"), is a white crystalline double sulfate usually encountered as the dodecahydrate, formula (NH 4)Al(SO 4) 2 ·12H 2 O. It is used in small amounts in a variety of niche applications.

  9. Ammonium persulfate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_persulfate

    Ammonium persulfate (APS) is the inorganic compound with the formula (NH 4) 2 S 2 O 8. It is a colourless (white) salt that is highly soluble in water, much more so than the related potassium salt .
