selenic acid formula

\(SeO_2+H_2O_2\rightarrow H_2SeO_4\) Seppelt, K. “Selenoyl difluoride” Inorganic Syntheses, 1980, volume XX, pp. It is a colorless compound. Selenic acid is a strong dibasic acid with the formula H 2 SeO 4.It can be manufactured by oxidising selenium compounds in lower oxidation states. ... Selenic acid solution. Selenic acid is the inorganic compound with the formula H 2SeO 4. It is an oxoacid of selenium, and its structure is more accurately described as (HO)2SeO2. It is prepared by oxidising selenium compounds in lower oxidation states. [3] In the solid state, it crystallizes in an orthorhombic structure.[4]. The molecular formula identifies each type of element by its chemical symbol and identifies the number of atoms of each element found in one discrete molecule of the substance. Selenic acid is the inorganic compound with the formula H2SeO4. And this should be told in more detail. b. It is an oxoacid of selenium, and its structure is more accurately described as (HO) 2SeO 2. In general, selenate salts resemble sulfate salts, but are more soluble. Selenic acid is the inorganic compound with the formula H 2SeO 4. Although it has few uses, its derivative sodium selenate is used in the production of glass and animal feeds. Proprietăți Fizice. Many selenate salts have the same crystal structure as the corresponding sulfate salts. Selenic acid is used as a specialized oxidizing agent. It is the principal oxoacid of selenium; the other being selenic acid. a.

It may oxidize organic matter such as wood, cotton, fiberboard, etc. It is a colorless compound. What is the oxidation state of tellurium in Te(OH) 6 ? One method involves the oxidation of selenium dioxide with hydrogen peroxide: Unlike the production sulfuric acid by hydration of sulfur trioxide, the hydration of selenium trioxide is an impractical method. [7], Like sulfuric acid, selenic acid is a strong acid that is hygroscopic and extremely soluble in water. 1 Product Result | Match Criteria: Product Name, Description Linear Formula: H 2 SeO 4. Selenous acid (or selenious acid) is the chemical compound with the formula H2SeO3. It can be manufactured by oxidising selenium compounds in lower oxidation states. Formula Weight. Its chemical formula is H2SeO4. [5] However, using chlorine or bromine as the oxidising agent also produces hydrochloric or hydrobromic acid as a side-product, which needs to be removed from the solution since they can reduce the selenic acid to selenous acid. [3] Instead, selenic acid may also be prepared by the oxidation of selenous acid (H2SeO3) with halogens, such as chlorine or bromine, or with potassium permanganate. [2], The molecule is tetrahedral, as predicted by VSEPR theory. [5] The monohydrate melts at 26 °C, and the dihydrate melts at −51.7 °C.[3]. In this short piece of article, we will be discussing more the selenic acid formula, its chemical structure properties and uses. Although it has few uses, its derivative sodium selenate is used in the production of glass and animal feeds. [6], Another method of preparing selenic acid is by the oxidation of elemental selenium in a water suspension by chlorine:[5], To obtain the anhydrous acid as a crystalline solid, the resulting solution is evaporated at temperatures below 140 °C (413 K; 284 °F) in a vacuum. The correct formula is H2Se. 9, 623 (1827); 11, 327 (1827); Ann. Literature References: Prepd by treating lead selenate with hydrogen sulfide and concentrating the filtered soln by evaporation: Mitscherlich, Pogg. One of the methods includes oxidising selenium dioxide with hydrogen peroxide.

Despite its structural differences with sulfuric and selenic acid, telluric acid is a diprotic acid with p K a 1 = 7.68 and p K a 2 = 11.29. The a Se–O bond length is 161 pm.
