What is PbCl2? Important knowledge about PbCl2.

  1. Definition of PbCl2

PbCl2, also known as Lead(II) chloride or Plumbous chloride, is a chemical compound formed from lead and chlorine atoms. Each molecule of PbCl2 consists of one lead atom and two chlorine atoms. The atomic mass of PbCl2 is 278.1 g/mol. The atoms in the molecule form an ionic structure with lead forming the lead (II) ion Pb2+ and chlorine forming the chloride ion Cl-.
