CAS RN: 301-04-2

Other Properties

Density: 1.69; MP: 22 deg C; white, rhombic crystals; insol in alc; sol in water /Lead acetate decahydrate/
Density: 2.55; MP: 75 deg C decomp; white, monoclinic crystals;/Lead acetate trihydrate/
Sweetish taste; white flakes (commercial grades are frequently brown or gray lumps) /Lead acetate trihydrate/
Insol in alc /lead acetate dihydrate/
Slowly effloresces. Takes up CO2 from air and becomes incompletely sol. Density 2.55 g/cu cm. Melting point 75 deg C when rapidly heated; at a little above 100 deg C it begins to lose acetic acid; decomposes completely above 200 deg C. One gram dissolves in 1.6 ml water, 0.5 ml boiling water, 30 ml alcohol; freely sol in glycerol. /Trihydrate/
Aq solns of lead acetate dissolve lead monoxide.
Intensely sweet taste. /Trihydrate/
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.
