Structure of selenate

The selenate ion is SeO42–.

Selenates are analogous to sulfates and have similar chemistry. They are highly soluble in aqueous solutions at ambient temperatures.

Unlike sulfate, selenate is a somewhat good oxidizer; it can be reduced to selenite or selenium.

In strongly acid conditions, hydrogen selenate ion, HSeO4, is formed. It corresponds to the selenic acid, H2SeO4, which is a strong acid.
