  2. 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 ...

  3. Ammonia solution - Wikipedia

    en.wikipedia.org/wiki/Ammonia_solution

    In aqueous solution, ammonia deprotonates a small fraction of the water to give ammonium and hydroxide according to the following equilibrium: . NH 3 + H 2 O ⇌ NH + 4 + OH −.. In a 1 M ammonia solution, about 0.42% of the ammonia is converted to ammonium, equivalent to pH = 11.63 because [NH +

    Table data (above) obtained from CRC Handbook of Chemistry and Physics 44th ed. The (s) notation indicates equilibrium temperature of vapor over solid. Otherwise temperature is equilibrium of vapor over liquid.

  5. Ammonium - Wikipedia

    en.wikipedia.org/wiki/Ammonium

    Ammonium is a modified form of ammonia that has an extra hydrogen atom. It is a positively charged molecular ion with the chemical formula NH + 4 or [NH 4] +.It is formed by the addition of a proton (a hydrogen nucleus) to ammonia (NH 3).

  6. Amine - Wikipedia

    Amine. In chemistry, amines (/ ə ˈ m iː n, ˈ æ m iː n /, [1] [2] UK also / ˈ eɪ m iː n / [3]) are compounds and functional groups that contain a basic nitrogen atom with a lone pair.Formally, amines are derivatives of ammonia (NH 3 (in which the bond angle between the nitrogen and hydrogen is 170°), wherein one or more hydrogen atoms have been replaced by a substituent such as an ...

    NH3, NH-3, NH 3 or NH 3 may refer to: Ammonia (chemical formula NH 3) National Highway 3 (India) National Highway 3 (India, old numbering) New Hampshire Route 3;

  8. Ammonia pollution - Wikipedia

    en.wikipedia.org/wiki/Ammonia_pollution

    This includes nitrogen based compounds like ammonium (NH 4 +) which, similar to manure, is released as ammonia through volatilization (into the atmosphere or in runoff). [10] [7] 3. Concentrated animal feeding operations (CAFOs) contribute largely to ammonia emissions. Studies show that ammonia emission rates were 700 kg/h and ammonia emissions ...
