The arsenate ion is AsO₄³⁻.

An arsenate (compound) is some compound that contains this ion.

See Arsenate for a list.

Arsenate is much like phosphate. In acid conditions we have arsenic acid, H₃AsO₄; in weakly acid conditions we have the dihydrogen arsenate ion, H₂AsO₄⁻; in weakly basic conditions we have hydrogen arsenate ion HAsO₄²⁻; and finally, in basic conditions, the arsenate ion AsO₄³⁻.
