tungstic
Adjective: - Of or relating to tungsten: "tungstic" describes something that contains or is derived from the chemical element tungsten (also known as wolfram). It is most commonly used in chemistry to refer to compounds where tungsten has a high oxidation state, especially tungsten in its +6 oxidation state.
- (An acid derived from tungsten.)
- (A protective coating containing tungsten.)
"tungstic acid": A specific chemical compound (H₂WO₄) that is a weak acid and a precursor to many tungsten compounds.
- In the laboratory, tungstic acid is precipitated by adding a strong acid to a solution of a tungstate salt. (A common chemical reaction involving the target word.)
"tungstic oxide": Another term for tungsten trioxide (WO₃), a compound often used in electrochromic devices and as a catalyst.
- Tungstic oxide changes color when an electric current is applied, making it useful for smart windows. (A practical application of the compound.)
Tungsten (n): the chemical element (symbol W, atomic number 74) from which "tungstic" is derived.
- Tungsten has the highest melting point of any metal. (The base element.)
Tungstate (n): a salt or ester of tungstic acid, containing the WO₄²⁻ ion.
- Sodium tungstate is used as a corrosion inhibitor. (A related compound.)
- Wolframic: an alternative term meaning the same as "tungstic," derived from the element's other name, wolfram.
- Wolframic acid is chemically identical to tungstic acid. (An exact synonym.)
- "Tungstic" is a highly specialized technical term and does not appear in idiomatic expressions.
