LEAD(II) SULFATE Usage And Synthesis
  • Physical PropertiesWhite monoclinic or rhombic crystals; refractive index 1.877; density 6.20 g/cm3; melts at 1,170°C; very slightly soluble in water, 42.5 mg/L at 25°C; KSP1.82x10–8; sparingly soluble in hydrochloric and nitric acids; slightly soluble in dilute sulfuric acid, more soluble in concentrated sulfuric acid; insoluble in alcohol; soluble in caustic soda and ammonium salts solutions.
  • Occurrence and UsesLead sulfate occurs in nature as the mineral, anglesite. It is an essential component of lead-sulfuric acid storage batteries and forms during discharge cycles. It is used as an additive to stabilize clay soil for construction. Other applications are in photography and as a pigment.
  • PreparationLead sulfate precipitates when an aqueous solution of lead nitrate or other soluble salt of lead is treated with sulfuric acid.
    Alternatively, lead sulfate may be prepared by treating lead oxide, hydroxide, or carbonate with concentrated sulfuric acid under warm condition. It also is produced when lead sulfide is roasted in air.
  • ToxicityLow to moderate toxicity by ingestion. Irritant action on eye, skin, and mucous membranes.
  • Chemical Propertieswhite crystals or powder
  • Chemical PropertiesLead sulfate is a heavy, white crystalline powder.
  • UsesAs pigment instead of white lead; manufacture of galvanic and lead-acid batteries; manufacture of minium, in lithography; preparing rapidly drying oil varnishes; weighting fabrics.
  • UsesIt has been used in photography in combination with silver bromide and is used in the stabilization of clay soil for adobe structures, earth-fill dams, and roads.
  • Definitionanglesite: A mineral form oflead(II) sulphate, PbSO4.
  • Production MethodsLead sulfate, PbSO4, is soluble in concentrated acids and alkalies, forming hydroxyplumbites. It is prepared by treating lead oxide, hydroxide, or carbonate with warm sulfuric acid, or by treating a soluble lead salt with sulfuric acid.
  • General DescriptionA white crystalline solid. Insoluble in water and sinks in water. Contact may irritate skin, eyes, and mucous membranes. May be mildly toxic by ingestion, inhalation and skin absorption. Used to make other chemicals. Use: in lithography, battery acid solution treated fabrics, used in varnishes.
  • Air & Water ReactionsInsoluble in water.
  • Reactivity ProfileLEAD(II) SULFATE reacts explosively with boric acid [Bretherick 1979. p. 1029]. Special Hazards of Combustion Products: Toxic metal fumes [USCG, 1999].
  • Health HazardINHALATION: Joint and muscle pains, headache, dizziness and insomnia. Weakness, frequently of extensor muscles of hand and wrist (unilateral or bilateral). Heavy contamination. Brain damage. Stupor progressing to coma - with or without convulsion, often death. Excitation, confusion, and mania less common. Cerebrospinal pressure may be increased. EYES: Caused a moderat purulent reaction and general inflammation of the rabbit eye. INGESTION: Abdominal pain, diarrhea, constipation, loss of appetite, muscular weakness, headache, blue line on gums, metallic taste, nausea and vomiting.
  • Fire HazardSpecial Hazards of Combustion Products: Toxic metal fumes
  • Potential ExposureLead sulfate is used in storage batteries and paint pigments. Used in the making of alloys, fastdrying oil varnishes; weighting fabrics; in lithography
