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. It is the principal oxoacid of selenium; the other being selenic acid. It is a colorless compound. [2], The molecule is tetrahedral, as predicted by VSEPR theory. Concentrated solutions are viscous. One of the methods includes oxidising selenium dioxide with hydrogen peroxide. Proprietăți Fizice. Chemistry Chemistry While selenic acid has the formula H 2 SeO 4 and thus is directly related to sulfuric acid, telluric acid is best visualized as H 6 TeO 6 or Te(OH) 6 ? And this should be told in more detail. Formula Weight. 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. SELENIC ACID, LIQUID reacts exothermically with chemical bases (for example: amines and inorganic hydroxides) to form salts. 9, 623 (1827); 11, 327 (1827); Ann. It can be manufactured by oxidising selenium compounds in lower oxidation states. Although it has few uses, its derivative sodium selenate is … [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. To learn more about such chemistry topics register to BYJU’S now! The reactions can generate dangerously large amounts of heat in small spaces. The formula for the selenate ion is SeO42-. Your email address will not be published. In this short piece of article, we will be discussing more the selenic acid formula, its chemical structure properties and uses. any ideas? 36-38. https://en.wikipedia.org/w/index.php?title=Selenic_acid&oldid=981000726, Pages using collapsible list with both background and text-align in titlestyle, Articles containing unverified chemical infoboxes, Creative Commons Attribution-ShareAlike License, This page was last edited on 29 September 2020, at 18:17. Although it has few uses, its derivative sodium selenate is used in the production of glass and animal feeds. 101 - 200 (1) Available for Sale. Because it is an acid, hydrogen needs to be at the beginning. [3], Treatment with fluorosulfuric acid gives selenoyl fluoride:[7], Hot, concentrated selenic acid reacts with gold, forming a reddish-yellow solution of gold(III) selenate:[8]. Selenic acid is a stronger oxidizer than sulfuric acid,[5] capable of liberating chlorine from chloride ions, being reduced to selenous acid in the process: It decomposes above 200 °C, liberating oxygen gas and being reduced to selenous acid:[5], Selenic acid reacts with barium salts to precipitate BaSeO4, analogous to the sulfate. Bernd E. Langner "Selenium and Selenium Compounds" in Ullmann's Encyclopedia of Industrial Chemistry, 2005, Wiley-VCH, Weinheim. Selenic acid is the inorganic compound with the formula H2SeO4. Its chemical formula is H2SeO4. It is an oxoacid of selenium, and its structure is more accurately described as (HO) 2SeO 2. What is the oxidation state of tellurium in Te(OH) 6 ? Crystalline mono- and di-hydrates are known. Many selenate salts have the same crystal structure as the corresponding sulfate salts. It is a colorless compound. Selenic acid is used as a specialized oxidizing agent. 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. b. Structurally, it is more accurately described by (HO)2SeO. One of the methods includes oxidising selenium dioxide with hydrogen peroxide.
