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 ]
The metatellurate anion has a chemical shift around 610 ppm when analyzed using 125 Te NMR at 25 °C at a frequency of 94.735 MHz and referenced externally against aqueous 1.0 M telluric acid. [ 6 ] The tellurate suffix in the naming of inorganic compounds
The tellurium oxides and hydrated oxides form a series of acids, including tellurous acid (H 2 TeO 3), orthotelluric acid (Te(OH) 6) and metatelluric acid ((H 2 TeO 4) n). [9] The two forms of telluric acid form tellurate salts containing the TeO 2– 4 and TeO 6− 6 anions, respectively. Tellurous acid forms tellurite salts containing the ...
Compounds that contain the anions follow basic nomenclature rules, the cation is named first, followed by the anion. [2] As individual ions current IUPAC naming conventions dictate that compounds containing what was conventionally known as the tellurite ion, [TeO 3 ] 2- , be named as tellurate (IV) compounds, while other tellurates are labeled ...
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]
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−
Amorphous tellurium is a black-brown powder prepared by precipitating it from a solution of tellurous acid or telluric acid (Te(OH) 6). [13] Tellurium is a semiconductor that shows greater electrical conductivity in certain directions depending on atomic alignment; the conductivity increases slightly when exposed to light ( photoconductivity ...
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.
