    Lead sulphate PbSO4, also called "lead sulphate", precipitates as a white powdery precipitate when dilute sulfuric acid is added to lead salt solutions. It is hardly soluble in water (about 40 mg / l). It dissolves much better in concentrated strong acids (hydrochloric, nitric, sulfuric). When diluted, most of it falls out again.
    Sodium and ammonium acetate solutions are also capable of dissolving significant amounts of lead sulfate. The solubility of lead sulfate in ammonium tartrate solutions containing ammonia is used in the analysis for its determination and separation from other water-insoluble white powdery substances, such as barium sulfate, silicon dioxide, etc. which do not dissolve in ammonium tartrate.
    An increase in the solubility of PbSO4 in the presence of these substances is explained by the formation of weaker dissociating compounds with them (for example, the formation of little dissociated lead acetate with the addition of acetate ions) and partly the formation of complexes.
    Lead sulfate also dissolves in concentrated alkali solutions; in this case with the formation of hydroxoplumbates (II) of alkali metals.
    In nature, lead sulfite is often found in the form of well-formed large crystals of the rhombic system of specific gravity 6.1-6.4; it is anglesite (vitriol lead ore). In their pure state, these crystals are transparent, like glass (which is why they are also called "lead glass"). However, they often contain coloring impurities.
    In addition to the rhombic modification, lead sulfate also exists in monoclinic. In some deposits it is found in this form (for example, in Sardinia).
    The melting point of lead sulfate lies between 1150-1200 ° C. It is not possible to determine it more precisely, since this compound starts to decompose at 1000 ºС.
    Lead sulphate can add lead oxide to form basic salts. It also forms double salts, for example, (NH4) 2Pb (SO4) 2 - fine, transparent, like water, crystals.
