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 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]
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.
Tellurite (TeO₃²⁻) is a highly toxic oxyanion of tellurium with notable biological activity, particularly due to its toxic effects on various organisms, including bacteria, plants, and humans. The lack of mitochondrial proteins MRPL44, NAM9 (MNA6) and GEP3 (MTG3) in yeast is associated with resistance to tellurite.
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.
Potassium compounds are those chemical compounds which contain the chemical element potassium. Subcategories This category has the following 3 subcategories, out of 3 total.
An alternative way of writing its formula is (HO) 2 TeO. In principle, tellurous acid would form by treatment of tellurium dioxide with water, that is by hydrolysis. The related conjugate base is well known in the form of several salts such as potassium hydrogen tellurite, KHTeO 3 .
