What is the solubility of PbS?
PbS shows a very low solubility in water, and it is insoluble in organic solvents. Any “dissolution” process in acids (hydrochloric acid, nitric acid, aqua regia) is accompanied with a chemical reaction whereby H2S is liberated and the corresponding soluble Pb2+ salts are formed.
Is lead II sulfide a precipitate?
Lead sulfide (PbS) is an insoluble metal sulfide in water. It forms a black precipitate in the water. PbS dissolve in nitric acid. Solubility data proves PbS is a precipitate in water.
Is lead II sulfide soluble?
Lead(II) sulfide is used as a semiconductor. Used in electronic devices and Infrared sensor. Soluble in water (0.00086g/L) and acid. Insoluble in alcohol, and potassium hydroxide.
Is PbS a sulfide?
Lead sulfide is an inorganic compound with the chemical formula PbS. It is also known as galena, which is the principal ore and important compound of lead. It is one of the earliest materials to be used as a semiconductor as it tends to crystallize in sodium chloride.
What is the formula for lead II sulfide?
PbSLead(II) sulfide / Formula
Is PbS insoluble?
Lead sulfide is insoluble and a stable compound in the pH of blood and so is probably one of the less toxic forms of lead. A large safety risk occurs in the synthesis of PbS using lead carboxylates, as they are particularly soluble and can cause negative physiological conditions.

Is lead II sulfate soluble in water?
Lead sulfate appears as a white crystalline solid. Insoluble in water and sinks in water.
Is lead sulfate soluble in water?
Is lead sulfide polar?
Lead sulphide (PbS) is a polar semiconductor crystallizing in the rocksalt crystal structure.
What is the formula for PbS?
How is lead sulfide removed from the air?
Lead (II) sulfide is expected to exist solely in the particulate phase in the ambient atmosphere which will be removed from the air by wet and dry deposition. Lead (II) sulfide will not leach in soil because it is relatively insoluble.
What is lead (II) sulfide?
Lead (II) sulfide is formed naturally from other lead compounds in reducing environments when sulfur is available. Lead (II) sulfide is expected to exist solely in the particulate phase in the ambient atmosphere which will be removed from the air by wet and dry deposition.
