  2. 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 +

  3. Ammonia - Wikipedia

    en.wikipedia.org/wiki/Ammonia

    Ammonia is moderately basic; a 1.0 M aqueous solution has a pH of 11.6, and if a strong acid is added to such a solution until the solution is neutral (pH = 7), 99.4% of the ammonia molecules are protonated. Temperature and salinity also affect the proportion of ammonium [NH 4] +.

  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. pH - Wikipedia

    en.wikipedia.org/wiki/PH

    The pH range is commonly given as zero to 14, but a pH value can be less than 0 for very concentrated strong acids or greater than 14 for very concentrated strong bases. [2] The pH scale is traceable to a set of standard solutions whose pH is established by international agreement. [3]

  7. Ammonium carbamate - Wikipedia

    en.wikipedia.org/wiki/Ammonium_carbamate

    Ammonium carbamate is a chemical compound with the formula [NH 4][H 2 NCO 2] consisting of ammonium cation NH + 4 and carbamate anion NH 2 COO −.It is a white solid that is extremely soluble in water, less so in alcohol.

  8. Ammonia pollution - Wikipedia

    en.wikipedia.org/wiki/Ammonia_pollution

    Freshwaters tend to have a wide range of pH values from 6.5 to 9. [25] Freshwaters that have a higher pH would be more sensitive to increases in ammonia due to the balance between ammonia and ammonium and the aquatic life would be more affected. The ammonia causes stress on the fish and damages internal organs which will eventually lead to ...

  9. Weak base - Wikipedia

    en.wikipedia.org/wiki/Weak_base

    Given its greater H + concentration, the formula yields a lower pH value for the weak base. However, pH of bases is usually calculated in terms of the OH − concentration. This is done because the H + concentration is not a part of the reaction, whereas the OH − concentration is. The pOH is defined as:
