Selenic and telluric acid\n08.02.2017\n\n\n\nAppropriate highly oxidation of selenium and telluric acid is produced by strong oxidants (chloric acid, chromic acid) on celine or telluric acid. They are separated in a free state and are colourless crystalline substances well soluble in water. Two celenic acid crystalline hydrates are known: h2seo4 * h2o and h2seo4 * 4h2o. Pure selenic acid can be obtained by acting sulfuric acid on barium selenate: baseo4 + h2so4 = baso4 + h2seo4. Concentrated selenic acid is a strong oxidant superior in this respect to concentrated sulphuric acid lot (so h2seo4 dissolves not only silver, but also gold). Crystalline hydrohydrate h2teo4 * 2h2o is released when the solution of telluric acid is evaporated. The characteristic feature of hydrogen atoms, which are part of this crystalline hydrate, is the ability to be partially or completely replaced by metal. For example, ag6teo6 salt is known for its response to h6teo6 basic (so-called orthothelluric) acid. Unlike selenic acid, telluric acid is very weak. Telluric acid is restored with sulfur gas to elemental telluric acid. In the meantime, selenic acid is recovered by this reducer only to selenic acid. It can be used to separate tellurium and selenium.\n\n\n\n\n\nContact facebookclassmate mirtwitterlivejournalselenites and tellurioxidizes selenium and tellurioxidizes selenium and tellurization Germanic waste getting Germany monocrystalline waste getting Germany high purity getting Germany high purity and Germany monocrystalls with specified electrical properties getting Germany extraction from waste processing coal recovery Germany from waste zinc production
