Definition

1. Noun:
   • A salt or ester of vanadic acid: A chemical compound formed when vanadic acid reacts with a base or an alcohol.
   • An anion containing pentavalent vanadium: A negatively charged ion (anion) that includes vanadium in its +5 oxidation state.

Usage Examples

• Noun:
  • Ammonium vanadate is a common reagent in chemical laboratories.
  • The mineral carnotite is a source of uranium and vanadate ions.

Advanced Usage

• In Chemistry: The term is used specifically in inorganic and mineral chemistry to describe compounds where the vanadate anion (e.g., VO₄³⁻) is combined with various cations.
  • The structure of the vanadate anion is tetrahedral, similar to phosphate.

Variants and Related Words

• Vanadic (adj): Relating to vanadium, especially in a pentavalent state.
  • Vanadic acid is the precursor to vanadate salts.
• Vanadinite (n): A mineral consisting of lead chlorovanadate, Pb₅(VO₄)₃Cl.
• Metavanadate (n): A vanadate containing the polymeric anion (VO₃⁻)ₙ.

Synonyms

• Vanadium salt (when referring to the ionic compound form).

Notes

• Vanadates are often discussed in the context of their chemical behavior, industrial applications (e.g., catalysts), and occurrence in minerals. They are structurally and chemically analogous to phosphates.
