  2. Ammonia solution - Wikipedia

    en.wikipedia.org/wiki/Ammonia_solution

    Ammonia solution, also known as ammonia water, ammonium hydroxide, ammoniacal liquor, ammonia liquor, aqua ammonia, aqueous ammonia, or (inaccurately) ammonia, is a solution of ammonia in water. It can be denoted by the symbols NH 3 (aq). Although the name ammonium hydroxide suggests a salt with the composition [NH + 4][OH −

    Household ammonia or ammonium hydroxide is a solution of ammonia in ... 4 NH 3 + 3 O 2 → 2 N 2 + 6 H 2 O(g), ... to remove hair from hides in preparation for ...

  4. Hydroxylamine - Wikipedia

    en.wikipedia.org/wiki/Hydroxylamine

    Ammonium sulfate, [NH 4] 2 SO 4, a side-product insoluble in liquid ammonia, is removed by filtration; the liquid ammonia is evaporated to give the desired product. [4] The net reaction is: 2 NO − 2 + 4 SO 2 + 6 H 2 O + 6 NH 3 → 4 SO 2− 4 + 6 [NH 4] + + 2 NH 2 OH. A base then frees the hydroxylamine from the salt:

  5. Ammonium sulfite - Wikipedia

    en.wikipedia.org/wiki/Ammonium_sulfite

    Ammonium sulfite can be prepared by the reaction of ammonia with sulfur dioxide in aqueous solution: . 2 NH 3 + SO 2 + H 2 O → (NH 4) 2 SO 3. Ammonium sulfite is produced in gas scrubbers, now obsolete, consisting of ammonium hydroxide to remove sulfur dioxide from emissions from power plants.

  6. Tetramethylammonium hydroxide - Wikipedia

    en.wikipedia.org/wiki/Tetramethylammonium_hydroxide

    Tetramethylammonium hydroxide (TMAH or TMAOH) is a quaternary ammonium salt with molecular formula N(CH 3) 4 + OH −. It is commonly encountered in form of concentrated solutions in water or methanol. TMAH in solid state and its aqueous solutions are all colorless, but may be yellowish if impure.

  7. Ammonium iodate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_iodate

    Using its low solubility in water, it can also be precipitated from an iodate solution with an ammonium salt. 2 KIO 3 + (NH 4) 2 SO 4 → 2 NH 4 IO 3 + K 2 SO 4. Unlike other iodates, ammonium iodate can't be prepared by dissolving iodine in an ammonium hydroxide solution, instead the highly explosive nitrogen triiodide is formed. 3 I 2 + 5 NH ...

  8. Tetramethylammonium - Wikipedia

    en.wikipedia.org/wiki/Tetramethylammonium

    Tetramethylammonium (TMA) is the simplest quaternary ammonium cation. It has the chemical formula [Me 4 N] + and consists of four methyl groups (−CH 3, denoted Me) attached to a central nitrogen atom. The cation is isoelectronic with neopentane (Me 4 C). It is positively-charged and can only be isolated in association with a counter-ion.

  9. Ammonium heptamolybdate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_heptamolybdate

    Ammonium heptamolybdate is the inorganic compound whose chemical formula is (NH 4) 6 Mo 7 O 24, normally encountered as the tetrahydrate.A dihydrate is also known. It is a colorless solid, often referred to as ammonium paramolybdate or simply as ammonium molybdate, although "ammonium molybdate" can also refer to ammonium orthomolybdate, (NH 4) 2 MoO 4, and several other compounds.
