. Some have third anions.

Naming

A selenate selenite compound may also be called a selenite selenate.

Production

One way to produce a selenate selenite compound is to evaporate a water solution of selenate and selenite compounds.

Properties

On heating, selenate selenites lose SeO₂ and O₂ and yield selenites, and ultimately metal oxides.
