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.
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−
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 ]
Na 2 Te, like many related compounds with the formula M 2 X, adopts the antifluorite structure. Thus, in solid Na 2 Te each Te 2− ion is surrounded by eight Na + ions and each Na + ion is surrounded by four Te 2− ions. [3] Simple salts of the type M 2 X, where X is a monatomic anion, are not typically soluble in any solvent because they ...
Structure of tellurium tetrachloride, tetrabromide and tetraiodide. The +2 oxidation state is exhibited by the dihalides, TeCl 2, TeBr 2 and TeI 2.The dihalides have not been obtained in pure form, [3]: 274 although they are known decomposition products of the tetrahalides in organic solvents, and the derived tetrahalotellurates are well-characterized:
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.
Water can dissolve the other hydrogen chalcogenides (at least those up to hydrogen telluride), forming acidic solutions known as hydrochalcogenic acids. Although these are weaker acids than the hydrohalic acids , they follow a similar trend of acid strength increasing with heavier chalcogens, and also form in a similar way (turning the water ...
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.
