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
Mineral Rock forming minerals – typically silicates or occasionally carbonates – have a specific gravity of 2.5–3.5. High specific gravity is a diagnostic property of a mineral. A variation in chemistry (and consequently, mineral class) correlates to a change in specific gravity. Among more common minerals, oxides and sulfides tend to have a higher specific gravity as they include elements with higher atomic mass. A generalization is that minerals with metallic or adamantine lustre tend to have higher specific gravities than those having a non-metallic to dull lustre. For example, hematite, FeO, has a specific gravity of 5.26 while galena, PbS,
