The compound NH3 contains one atom of nitrogen and three atoms of hydrogen, whereas NH4 contains one atom of nitrogen and four atoms of hydrogen. NH3 is the chemical formula for ammonia, and NH4 is the chemical formula for ammonium. Both ammonia and ammonium are cations, meaning that they each carry a positive charge, which is +1 for both ions.


Ammonia from the gills of fish, their urine, and rotting food or decaying plant matter are contributors of ammonia in an aquarium. It exists in two forms in the aquarium and the first step is to understand the difference between ammonium NH4 and free ammonia NH3.


The formation of NH4+ from NH3 is sometimes decribed as the formation of a coordinate bond between NH3 and H+ , however once the bond is formed there is no difference between the four N-H bonds ...


You might want to qualify this question. Ammonia, [math]NH_{3}[/math], is a small molecule, and yet it has a relatively elevated normal boiling point of [math]-33.3[/math] [math]°C[/math]. And its involatility is consistent with the normal boiling...


NH3 – Ammonia. NH3 is the toxic form of ammonia to shrimp. It is only present when pH is higher, in the safe ranges for shrimp (above 7.5), and exists actually as a gas suspended in between the water molecules. NH3 is also referred to as un-ionized ammonia (compared to its ionized cousin, NH4).


NH3-N (or simply ammonia, NH3) and NH4-N are two different form of inorganic nitrogen. The one is the unionized form and the latter is the ionized form and very toxic.


Ammonia (NH3) and Ammonium (NH4) are in equilibrium when dissolved in water. The proportion of NH3 and NH4+ in the sample will vary based on pressure, temperature and most importantly pH. In basic solutions ammonia is the dominant species. This is important to note when comparing to other instrumentation that may read as NH3 or NH3-N.


The key difference between ammonia and ammoniacal nitrogen is that the ammonia is an inorganic compound having the chemical formula NH3 whereas the ammoniacal nitrogen is a measure of the amount of ammonia in a sample.. Ammonia is a gaseous compound with a characteristic, pungent odor. Although it is useful on many occasions, it is a toxic compound as well.


NH3 is not a cation - it is polar but uncharged. however, when NH3 is dissolved in water, it forms NH4+ and OH-, and NH4 is a cation. Asked in The Difference Between , Biology , Chemistry What is ...


The key difference between ammonia and ammonium hydroxide is that ammonia occurs as a gas while ammonium hydroxide occurs as a liquid at room temperature.. Ammonia and ammonium hydroxide have many uses for us. We all know that ammonia is a pungent smelling gas with a chemical formula NH3. When it comes in contact with water, what we get is ammonium hydroxide.
