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
Galena Historic District Places. The Galena Historic District contains more than 1,000 buildings constructed before 1900 that are considered contributing properties. The center of downtown Galena is laid out in three parallel segmental tiers starting at Main Street closest to the river. Beyond Main Street, and at a higher elevation, are Bench and Prospect Streets. Main Street forms the primary commercial strip through Galena and is lined with buildings two, three, and four stories tall. Most of Main Street's structures are built of red brick and cast in Federal style of the simple commercial style of the 1840s. On Bench Street, most of
