Definition

1. Noun:
   • A salt of tungstic acid: A chemical compound formed when tungstic acid reacts with a base or basic oxide, containing the tungstate anion (WO₄²⁻ or related polymeric forms).

Usage Examples

• Noun:
  • Calcium tungstate is a common mineral.
  • The chemist synthesized a sodium tungstate solution for the experiment.
  • Tungstates are often used as catalysts in industrial processes.

Advanced Usage

• "Polytungstate": A complex anion formed by the condensation of tungstate units, often found in isopoly- and heteropoly acids.
  • The researcher studied the structure of a phosphotungstate anion.
• "Metatungstate": A specific type of tungstate ion with a defined polymeric structure.
  • Ammonium metatungstate is a common precursor for tungsten compounds.

Variants and Related Words

• Tungstic (adj): Relating to or containing tungsten, especially in a high valence state.
  • Tungstic oxide is a yellow powder.
• Tungsten (n): The metallic element (symbol W, atomic number 74) from which tungstates are derived.
• Wolframate (n): A synonym for tungstate, derived from the alternative name for tungsten, wolfram.
