User:Graeme Bartlett/fluoride selenate

From Wikipedia, the free encyclopedia

A selenate fluoride is a chemical compound or salt that contains fluoride and selenate anions (F- and SeO42-). These are mixed anion compounds. Some have third anions.

Naming

[edit]

A selenate fluoride compound may also be called a fluoride oxoselenate(VI) using IUPAC naming for inorganic compounds.

Production

[edit]

One way to produce a fluoride selenate compound is to evaporate a water solution of selenate and fluoride compounds.[1]

[edit]

Related to these are the selenate chlorides and selenate bromides by varying the halogenide. Similar compounds by varying the chalcogen also include the sulfate fluorides, chromate fluorides and tellurate fluorides.
