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.
When a salt of a metal ion, with the generic formula MX n, is dissolved in water, it will dissociate into a cation and anions. [citation needed]+ + (aq) signifies that the ion is aquated, with cations having a chemical formula [M(H 2 O) p] q+ and anions whose state of aquation is generally unknown.
Ammonium tellurate is a chemical compound with the chemical formula ... 2 with hydrogen peroxide in an ammonia medium. Physical properties. Ammonium tellurate forms ...
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:
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.
All three are prepared by direct reaction of their elements at about 1,000 °C (1,832 °F) and quickly hydrolyse completely in water to yield aluminium hydroxide and the respective hydrogen chalcogenide. As aluminium is a small atom relative to these chalcogens, these have four-coordinate tetrahedral aluminium with various polymorphs having ...
Sodium tellurite is an inorganic tellurium compound with formula Na 2 TeO 3. It is a water-soluble white solid and a weak reducing agent . Sodium tellurite is an intermediate in the extraction of the element, tellurium; it is a product obtained from anode slimes and is a precursor to tellurium.
Organoaluminium chemistry is the study of compounds containing bonds between carbon and aluminium. It is one of the major themes within organometallic chemistry . [ 1 ] [ 2 ] Illustrative organoaluminium compounds are the dimer trimethylaluminium , the monomer triisobutylaluminium , and the titanium-aluminium compound called Tebbe's reagent .
