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 or protonated substituted amines and quaternary ammonium cations ([NR4] ), where one or more hydrogen atoms are replaced by organic groups (indicated by R). WebThe number and identity of the oxyanions that exist between pH 13 and 2 depend on pH as well as concentration. For example, protonation of vanadate initiates a series of condensations to produce polyoxovanadate ions: [2] pH 9–12: HVO2− 4, V2O4− 7 pH 4–9: H2VO− 4, V4O4− 12, HV10O5− 28 pH 2–4: H3VO4, H2V10O4− 28 Pharmacological …
