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.
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]
The anode sludges contain the selenides and tellurides of the noble metals in compounds with the formula M 2 Se or M 2 Te (M = Cu, Ag, Au). At temperatures of 500 °C the anode sludges are roasted with sodium carbonate under air. The metal ions are reduced to the metals, while the telluride is converted to sodium tellurite. [38]
However tellurate and tellurite are often referred to as tellurate(VI) and tellurate(IV) respectively in line with IUPAC renaming recommendations. [1] The metatellurate ion is TeO 2− 4 and the orthotellurate ion is TeO 6− 6. Other oxyanions include pentaoxotellurate, TeO 4− 5, [2] ditellurate, Te 2 O 8−
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.
