Ammonium Ion - an overview ScienceDirect Topics
The ammonium cation is a positively-charged polyatomic ion with the chemical formula NH+4 or [NH4] . It is formed by the protonation of ammonia (NH3). Ammonium is also a general name for positively charged (protonated) substituted amines and quaternary ammonium cations ([NR4] ), where one or … See more The ammonium ion is generated when ammonia, a weak base, reacts with Brønsted acids (proton donors): H + NH3 → [NH4] The ammonium ion is mildly acidic, reacting with … See more Ammonium ions are a waste product of the metabolism of animals. In fish and aquatic invertebrates, it is excreted directly into the water. In mammals, sharks, and amphibians, it is converted in the urea cycle to urea, because urea is less toxic and can be stored … See more • Onium compounds • Fluoronium, ([H2F] and substituted derivatives) • Oxonium ([R3O] , where R is typically hydrogen or organyl) • Hydronium ([H3O] , the simplest oxonium ion) See more Ammonium cation is found in a variety of salts such as ammonium carbonate, ammonium chloride, and ammonium nitrate. Most simple ammonium salts are very See more The hydrogen atoms in the ammonium ion can be substituted with an alkyl group or some other organic group to form a substituted … See more The ammonium cation has very similar properties to the heavier alkali metals cations and is often considered a close equivalent. Ammonium is expected to behave as a metal ([NH4] ions in a sea of electrons) at very high pressures, such as inside See more WebCâu hỏi 4 trang 56 Hóa học 11: Khi so sánh phân tử ammonia với ion ammonium, nhận định nào sau đây là đúng?
