Lead(II) sulfate primary lead sulfide ore, galena. A number of lead basic sulfates are known: PbSO·PbO; PbSO·2PbO; PbSO·3PbO; PbSO·4PbO. They are used in manufacturing of active paste for lead acid batteries. A related mineral is leadhillite, 2PbCO·PbSO·Pb(OH). At high concentration of sulfuric acid (>80%), lead hydrogensulfate, Pb(HSO), forms. Lead(II) sulfate can be dissolved in concentrated HNO, HCl, HSO producing acidic salts or complex compounds, and in concentrated alkali giving soluble hexahydroxidoplumbate(II) [Pb(OH)] complexes. Lead(II) sulfate decomposes when heated above 1000 °C: Lead(II) sulfate Lead(II) sulfate (PbSO) is a white solid, which appears white in microcrystalline form. It is also known as "fast
