Selenous acid can be used as a reagent to synthesize: α-Ketoacectals by reacting with acetophenones and triethylorthoformate in the presence of boron trifluoride etherate as a catalyst [1].

It is formed by the oxidation of selenious acid or elemental selenium with strong oxidizing agents in the presence of water. It is very soluble in water, as are most selenate salts.

Selenious acid is the acid form of sodium selenite, a form of selenium 8. Selenium is an essential trace element and antioxidant. It is a cofactor metabolic enzyme regulation. It also plays an important role …

Selenous acid, systematically named as selenic (IV) acid with molecular formula H₂SeO₃, represents the principal oxoacid of selenium in the +4 oxidation state. This inorganic compound exists as white …

Selenous acid is easily formed upon the addition of selenium dioxide to water. As a crystalline solid, the compound can be seen as pyramidal molecules that are interconnected with hydrogen bonds.
