Insoluble in water. | [Health Hazard]
INHALATION: 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. | [Potential Exposure]
Lead sulfate is used in storage batteries and paint pigments. Used in the making of alloys, fastdrying oil varnishes; weighting fabrics; in lithography | [Fire Hazard]
Special Hazards of Combustion Products: Toxic metal fumes | [First aid]
Move victim to fresh air. Call 911 or emergency
medical service. Give artificial respiration if victim is not
breathing. Do not use mouth-to-mouth method if victim
ingested or inhaled the substance; give artificial respiration
with the aid of a pocket mask equipped with a one-way
valve or other proper respiratory medical device.
Administer oxygen if breathing is difficult. Remove and
isolate contaminated clothing and shoes. In case of contact
with substance, immediately flush skin or eyes with running water for at least 20 minutes. Keep victim warm and
quiet. Effects of exposure (inhalation, ingestion or skin
contact) to substance may be delayed. Ensure that medical
personnel are aware of the material(s) involved and take
precautions to protect themselves. Medical observation is
recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. As first aid for
pulmonary edema, a doctor or authorized paramedic may
consider administering a drug or other inhalation therapy.
If this chemical gets into the eyes, remove any contact
lenses at once and irrigate immediately for at least 20 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the
skin, remove contaminated clothing and wash immediately
with soap and water. Seek medical attention immediately.
If this chemical has been inhaled, remove from exposure,
begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if
heart action has stopped. Transfer promptly to a medical
facility. When this chemical has been swallowed, get medical attention. Do not induce vomiting | [Shipping]

Lead sulfate is a heavy, white crystalline powder. | [Chemical Properties]
white crystals or powder | [Uses]
As pigment instead of white lead; manufacture of galvanic and lead-acid batteries; manufacture of minium, in lithography; preparing rapidly drying oil varnishes; weighting fabrics. | [Uses]
It 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. | [Uses]
Lead(II) sulfate is used in pigments, galvanic batteries, lithography, weighting fabrics. It is also used as intermediates. | [Definition]
anglesite: A mineral form oflead(II) sulphate, PbSO4. | [Production Methods]
Lead 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. | [storage]
Color Code—White: Corrosive or Contact Hazard;Store separately in a corrosion-resistant location. Prior toworking with this chemical you should be trained on its proper handling and storage. Lead sulfate must be stored toavoid contact with oxidizers (such as perchlorates, peroxides, permanganates, chlorates, and nitrates) and chemicallyactive metals (such as potassium, sodium, magnesium, andzinc), since violent reactions occur. Lead is regulated by anOSHA Standard 1910.1025. All requirements of the standard must be followed. A regulated, marked area should beestablished where this chemical is handled, used, or storedin compliance with OSHA Standard 1910.1045. |
| Questions And Answer | Back Directory | [Physical Properties]
White 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 Uses]
Lead 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.
| [Preparation]
Lead 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.
| [Toxicity]
Low to moderate toxicity by ingestion. Irritant action on eye, skin, and mucous membranes.
