Plumbi Acetas. Lead Acetate. Pb(C2H3O2)2+3H2O== 378.0. Synonym. - Sugar of Lead.

Source

Metallic Lead is dissolved, in the presence of air, in Acetic Acid. PbO+2C2H4O2+2H2O=Pb(C2H3O2)2+3H2O. To obtain well-defined crystals the solution must have a distinctly acid reaction.

Characters

Colorless, shining, transparent, monoclinic prisms or plates, or heavy, white, crystalline masses, or granular crystals, having a faintly acetous odor, and a sweetish, astringent, afterwards metallic taste. Efflorescent, and absorbing Carbon Dioxide, on exposure to the air. Solubility. - In 1.8 parts of water.
