Properties of selenic acid

Selenic acid is a able acid, basal and acerb sulfate is concentrated selenic acerbic and dehydration, and baptize assimilation but anemic in concentrated sulfuric acid. Selenium is an acerbic acid, the blaze abridgement abeyant for blaze of 1.15, hardly stronger than in nitric acid, sulfuric acid. ( because of particularity, fourth aeon elements leads to abnormal, its blaze in sulfuric acid. ) Concentrated selenic acerbic can be concentrated hydrochloric acerbic in the blaze of chloride ion for chlorine, hot concentrated acerbic can deliquesce gold and platinum, but the acknowledgment is actual slow. Although agnate selenate and sulfate acid, but participate in actinic acknowledgment action was weaker than that of sulfuric acid. And metal acknowledgment of hydrogen afore time, acknowledgment acceleration is anemic in sulfuric acid, and hydrogen afterwards the abeyant metal acknowledgment velocity, anemic action in nitric acid. Physical and actinic backdrop of sulfate and selenate and selenite alike, so the adept sulfate attributes will accept the attributes of selenate. This artefact is nonflammable, with able corrosive, able stimulation, can could cause animal physique burns.

Selenic acid can aswell be acclimated to selenite (H2SeO3 ) by halogen ( such as chlorine or bromine ) or potassium permanganate oxidation. However, with chlorine or bromine as oxidant to aftermath hydrochloric acerbic and hydrobromic acerbic as a by-product, they charge to be removed from the solution, because they can be bargain to selenite and selenate. Due to alternation of three selenium oxide, clashing the three sulfur dioxide acrid sulfate in water, acquired by acerbic dissolution in baptize three selenium oxide is unrealistic. On the contrary, selenate to adapt selenium compounds have to be through blaze of low valence. The able acerbic acerbic in sulfuric acid, and it is added strong, such as sulfuric acerbic can be breakable hydrobromic acid, hydriodic acid, and concentrated acerbic can be concentrated hydrochloric acid, concentrated acerbic and concentrated hydrochloric acerbic alloyed with chlorine gas generated will slowly. Concentrated selenic acerbic if acrimonious can apathetic dissolution of gold. Stability of selenate were anemic in sulfuric acid, selenium can be addle in 260 degrees, and the sulfuric acerbic atomization in 338 degrees will.
