Physical Description	Lead sulfate appears as a 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.Dry PowderWet SolidOther SolidLiquidWhite powder that is insoluble in water[CAMEO]
Other Experimental Properties	Lead is derived from the decay of radon. /Inorganic lead/Natural lead is a mixture of four stable isotopes: Pb-204 (1.4%), Pb-206 (25.2%), Pb-207 (21.7%) and Pb-208 (51.7%). Lead isotopes are the end-products of each of the three series of naturally occurring radioactive elements: Pb-206 for the uranium series, Pb-207 for the actinium series and Pb-208 for the thorium series. Forty-three other isotopes of lead, all of which are radioactive, are recognized.Divalent lead has a strong affinity for inorganic ions containing oxygen (eg, carbonate) or sulfur (sulfide). Lead can also complex with electron rich ligands in many organic cmpd such as amino acids, proteins, and humic acid.
