Definition of Pb4S
Commonly known as Lead Sulfide, Pb4S is a colorless, odorless solid that is insoluble in water. Its chemical formula is Pb4S, containing 4 lead atoms (Pb) and one sulfur atom (S). Pb4S has a molar mass of 1049.57 g/mol. The structure of Pb4S consists of lead ions Pb2+ and sulfide ions S2-, which combine together to form this compound. -
Properties of Pb4S
2.1 Physical properties of Pb4S: Pb4S is a solid at room temperature, colorless, odorless and insoluble in water. The pH of Pb4S cannot be determined because it is insoluble in water.
2.2 Chemical properties of Pb4S: Pb4S reacts very little with other substances. However, it can react with strong acids to produce sulfide ions and lead ions. -
Common chemical equation of Pb4S
As Pb4S reacts very little with other substances, there are no specific examples of reactions of Pb4S with metals, acids, nonmetals or salts. -
Synthesis of Pb4S
The synthesis of Pb4S is mainly performed in the laboratory. A common way is to let lead react with sulfur in an air environment, producing Pb4S. Currently, there is no detailed information on the industrial synthesis of Pb4S.
