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. The redox potential is −1.14 V. [2] Te(s) + 2 e − ↔ Te 2−
The labeling is arbitrary in initial choice, but once chosen fixed for the calculation. If any reference to an actual entity (say hydrogen ions H +) or any entity at all (say X) is made, the quantity symbol q is followed by curved ( ) brackets enclosing the molecular formula of X, i.e. q(X), or for a component i of a mixture q(X i).
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.
A Magic Triangle image mnemonic - when the terms of Ohm's law are arranged in this configuration, covering the unknown gives the formula in terms of the remaining parameters. It can be adapted to similar equations e.g. F = ma, v = fλ, E = mcΔT, V = π r 2 h and τ = rF sinθ.
