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.
TeO 2 + H 2 O 2 + 2 H 2 O → Te(OH) 6. Crystallization of telluric acid solutions below 10 °C gives telluric acid tetrahydrate Te(OH) 6 ·4H 2 O. [3] It is an oxidising agent, as shown by the electrode potential for the reaction below, although it is kinetically slow in its oxidations. [4] Te(OH) 6 + 2 H + + 2 e − ⇌ TeO 2 + 4 H 2 O, E o ...

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−
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 ...
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.
In this case, a three-fold rotoinversion with axis in the 111 direction is centred on the point (0, 0, 0) (where there is no ion) and can also be centred on the B ion at (1/2, 1/2, 1/2), and in fact every B ion is the centre of a three-fold rotoinversion (point group D 3d). Under this space group the two A positions are equivalent.
Crystal structure of sodium tellurite, highlighting the pyramidal structure of the anion. Tellurite dianion is pyramidal, like selenite and sulfite. The anion has C 3v symmetry. Tellurites can be reduced to elemental tellurium by electrolysis or a strong reducing agent. When fused with nitrate salts, tellurite salts oxidize to tellurates (TeO 2 ...
