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; the selenic acid, H2SeO4, is very strong.

See for a list.
