Lead(II) selenate is a selenate of lead, with the chemical formula PbSeO₄.

Preparation

Lead(II) selenate can be obtained by reacting a mixture of lead(II,IV) oxide and selenium dioxide with hydrogen peroxide.^[5] Lead(II) selenate is poorly soluble in water and can also be obtained through precipitation:^[6]
