vanadaattianioneja

Vanadaattianioneja refers to chemical compounds containing the vanadate anion. The vanadate anion is derived from vanadium, a transition metal, and oxygen. Vanadium commonly exists in oxidation states of +5 in vanadate species. The most prevalent vanadate anion is VO3- or vanadate(V), which is a linear ion. However, depending on the pH of the solution, other polyvanadate anions can form, such as pyrovanadate (V2O74-) and metavanadate (VO3-). In highly acidic conditions, the vanadyl cation, VO2+, may exist.

Vanadate compounds are found naturally in minerals like patronite and carnotite. Industrially, they are used in various applications. For instance, ammonium metavanadate (NH4VO3) is a common source of vanadium and is used in the production of ferrovanadium, an important alloy for steel. Vanadates also find use as catalysts in chemical reactions, particularly in the production of sulfuric acid. Certain vanadate compounds have been investigated for their biological activity, including potential medicinal properties, although their toxicity must also be considered. The color of vanadate compounds can vary depending on the specific anion and its coordination environment, often appearing yellow or orange.
