When ammonia is dissolved in water, a tiny amount of it converts to ammonium ions: H2O + NH3⇌ OH−+ [NH4]+. The degree to which ammonia forms the ammonium ion depends on the pHof the solution. See more 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 … 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 ammonium ion (IUPAC nomenclature: aminium ion). Depending on the number of organic groups, the ammonium cation … See more The ammonium cation has very similar properties to the heavier alkali metals cations and is often considered a close equivalent. … See more • Onium compounds • Fluoronium, ([H2F] and substituted derivatives) • Oxonium ([R3O] , where R is typically hydrogen or organyl) See more The ammonium ion is generated when ammonia, a weak base, reacts with Brønsted acids (proton donors): H + NH3 → [NH4] The ammonium 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 soluble in water. An exception is ammonium hexachloroplatinate, the formation of which … 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 See more
