| 单词 | ammonium ion |
| 例句 | Among the solubility rules previously discussed is the statement: Carbonates, phosphates, borates, and arsenates—except those of the ammonium ion and the alkali metals—are insoluble. Chemistry 2019-02-14T00:00:00Z Nitrogen is recycled in nature from organic compounds to ammonia, ammonium ions, nitrite, nitrate, and nitrogen gas. Biology for AP Courses 2022-06-09T00:00:00Z Prior to the urea cycle, ammonium ions are produced from the breakdown of amino acids. Anatomy and Physiology 2013-06-19T00:00:00Z It has an additional climate benefit, because it exudes compounds that prevent soil microbes from converting ammonium ions into potent greenhouse gases. World’s largest bean and cassava collection gets a striking new home 2022-03-20T04:00:00Z The match performed as he’d hoped: if he tried to tamper with the compounds, as a terrorist might, the iron and ammonium ions swapped, yielding iron nitrate and ammonium sulfate. How 'Unmaking' Explosives Might Save Soldiers' Lives 2013-05-28T18:20:17Z The ammonia acts as a base in accepting this proton, becoming an ammonium ion, the conjugate acid of ammonia. Chemistry 2019-02-14T00:00:00Z It is a macronutrient, and in nature, it is recycled from organic compounds to ammonia, ammonium ions, nitrate, nitrite, and nitrogen gas by myriad processes, many of which are carried out only by prokaryotes. Biology for AP Courses 2022-06-09T00:00:00Z In these reactions, an amine group, or ammonium ion, from the amino acid is exchanged with a keto group on another molecule. Anatomy and Physiology 2013-06-19T00:00:00Z Determinations of the electrical conductivity of the diazonium chloride and nitrate also show that the diazonium radical is strictly comparable with other quaternary ammonium ions. Encyclopaedia Britannica, 11th Edition, Volume 8, Slice 4 "Diameter" to "Dinarchus" The ammonium ion is similar in size to the potassium ion; compounds of the two ions exhibit many similarities in their structures and solubilities. Chemistry 2019-02-14T00:00:00Z In the reverse direction, a hydroxide ion acts as a base in accepting a proton from ammonium ion, which acts as an acid. Chemistry 2019-02-14T00:00:00Z In this oxidation-reduction reaction, the nitrogen in the nitrate ion oxidizes the nitrogen in the ammonium ion. Chemistry 2019-02-14T00:00:00Z This transamination event creates a molecule that is necessary for the Krebs cycle and an ammonium ion that enters into the urea cycle to be eliminated. Anatomy and Physiology 2013-06-19T00:00:00Z Hot ammonia and the ammonium ion are active reducing agents. Chemistry 2019-02-14T00:00:00Z Of particular interest are the oxidations of ammonium ion by nitrite ion, to yield pure nitrogen and by nitrate ion to yield nitrous oxide, N2O. Chemistry 2019-02-14T00:00:00Z A coordinate covalent bond also results when an ammonia molecule combines with a hydrogen ion to form an ammonium ion. Chemistry 2019-02-14T00:00:00Z |
