ammonium ionized form of ammonia.

the chemical structure ammonium nh+

4.

the chemical structure ammonia nh3.

ammonia highly soluble in water. ammonia reacts water (h2o) , forms ionized form:

nh3 + h2o ↔ nh+

4 + oh

the reaction reversible. hydroxide ion (oh) plus nh+

4 forms nh3 + h2o.

the percentage of ammonia increases increasing alkalinity of dissolved ammonium in water. ammonium ions formed increasing acidity of dissolved ammonia in water.

ammonia toxic fish , humans. toxicity decreased lower alkalinity , increases higher alkalinity ammonium converted ammonia.

ammonia , mineral forms of nitrogen

there 3 main forms of nitrogen:

molecular nitrogen
mineral nitrogen
organic nitrogen

molecular nitrogen

molecular nitrogen gas form of nitrogen in atmosphere. chemical structure nitrogen gas n2.

mineral nitrogen

the mineral forms of nitrogen are:

nitrate chemical structure of no−

3
nitrite chemical structure of no−

2
ammonium ions, chemical structure of nh+

4

ammoniums ions nitrified , converted microorganisms nitrate. fish , humans more tolerant of nitrate nitrogen of ammonium nitrogen. in aerated water, of mineral nitrogen in form of nitrate. see

organic nitrogen

major organic forms of nitrogen include proteins, amino acids, dna, , rna.
