Lead(II) selenate is a selenate of lead, with the chemical formula PbSeO4.
Preparation
[edit]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]
- Pb2+
+ SeO2−
4 → PbSeO
4↓
