Hydrogen telluride is the inorganic compound with the formula H 2 Te.A hydrogen chalcogenide and the simplest hydride of tellurium, it is a colorless gas.Although unstable in ambient air, the gas can exist long enough to be readily detected by the odour of rotting garlic at extremely low concentrations; or by the revolting odour of rotting leeks at somewhat higher concentrations.
Telluric acid, or more accurately orthotelluric acid, is a chemical compound with the formula Te(OH) 6, often written as H 6 TeO 6. It is a white crystalline solid made up of octahedral Te(OH) 6 molecules which persist in aqueous solution. [ 3 ]
They take on a bent structure and as such are polar molecules. Water is an essential compound to life on Earth today, [ 2 ] covering 70.9% of the planet's surface. The other hydrogen chalcogenides are usually extremely toxic, and have strong unpleasant scents usually resembling rotting eggs or vegetables.
These are mixed anion compounds, meaning the compounds are cations that contain one or more anions. Some have third anions. Some have third anions. Environmentally, tellurite [TeO 3 ] 2- is the more abundant anion due to tellurate's [TeO 4 ] 2- low solubility limiting its concentration in biospheric waters.
This salt is the conjugate base of the thermally unstable acid hydrogen telluride, but it is usually prepared by reduction of tellurium with sodium. Na 2 Te is a challenging material to handle because it is very sensitive to air. Air oxidizes it initially to polytellurides, which have the formula Na 2 Te x (x > 1), and ultimately Te metal.
Tellurous acid is an inorganic compound with the formula H 2 TeO 3. It is the oxoacid of tellurium(IV). [2] This compound is not well characterized. 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 structure of metatellurate and orthotellurate. In chemistry, tellurate is a compound containing an oxyanion of tellurium where tellurium has an oxidation number of +6. In the naming of inorganic compounds it is a suffix that indicates a polyatomic anion with a central tellurium atom. [1]
Hydrogen ditelluride or ditellane is an unstable hydrogen dichalcogenide containing two tellurium atoms per molecule, with structure H−Te−Te−H or (TeH) 2.Hydrogen ditelluride is interesting to theorists because its molecule is simple yet asymmetric (with no centre of symmetry) and is predicted to be one of the easiest to detect parity violation, in which the left handed molecule has ...
