Chemical formula. K 2 TeO 3 Appearance white crystals, powder Hazards GHS labelling: ... Potassium tellurite, K 2 TeO 3, is an inorganic potassium-tellurium compound. [1]
Potassium telluride is an inorganic compound with a chemical formula K 2 Te. It is formed from potassium and tellurium, making it a telluride. [2] Potassium telluride is a white powder. Like rubidium telluride and caesium telluride, it can be used as an ultraviolet detector in space.
The telluride ion is the anion Te 2− and its derivatives. It is analogous to the other chalcogenide anions, the lighter O 2−, S 2−, and Se 2−, and the heavier Po 2−. [1] In principle, Te 2− is formed by the two-e − reduction of tellurium. The redox potential is −1.14 V. [2] Te(s) + 2 e − ↔ Te 2−
Tellurite is a oxyanion of tellurium with the formula TeO 2− 3. It is the ion of tellurous acid, and is chemically related to tellurium dioxide (TeO 2), whose mineral appearance also bears the name tellurite. Tellurites are typically colorless or white salts, which in some ways are comparable to sulfite. [3]
A tellurite tellurate is a chemical compound or salt that contains tellurite and tellurate anions [TeO 3] 2-[TeO 4] 2-. These are mixed anion compounds , meaning the compounds are cations that contain one or more anions.
The metatellurate ion TeO 2− 4 is analogous to the sulfate ion, SO 2− 4 and the selenate ion, SeO 2− 4.Whereas many sulfates and selenates form isomorphous salts [5] the tetrahedral metatellurate ion is only found in a few compounds such as the tetraethylammonium salt (NEt 4) 2 TeO 4. [6]
2 I 2− 6, [3]: 283 and the black Te 4 I 2− 14. [3]: 285 With fluorine Te forms the mixed-valence Te 2 F 4 and TeF 6. In the +6 oxidation state, the –OTeF 5 structural group occurs in a number of compounds such as HOTeF 5, B(OTeF 5) 3, Xe(OTeF 5) 2, Te(OTeF 5) 4 and Te(OTeF 5) 6. [4] The square antiprismatic anion TeF 2− 8 is also ...
