Description General description Prepared by reacting lead(II) oxide /acetate or carbonate with HCl. In crystalline PbCl2, each atom is coordinated by nine Cl atoms, six of which lie at the apices of a trigonal prism and the remaining three beyond the centers of the three prism faces. Each Cl is coordinated by four or five Pb atoms. Upon exposure to air it form basic chlorides such as PbCl2.Pb(OH)2. Packaging 10, 50 g in poly bottle
