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; the selenic acid, H₂SeO₄, is very strong.
