Lead(II) sulfide - Infogalactic: the planetary knowledge core

Formation, basic properties, related materials Addition of hydrogen sulfide or sulfide salts to a solution of lead ions gives PbS as an insoluble black precipitate. Pb 2+ + H 2 S → PbS + 2 H + The equilibrium constant for this reaction is 3 × 10 6 M. This reaction, which entails a dramatic color change from colourless or white to black, was once used in qualitative inorganic analysis.

Lead Sulfides - an overview | ScienceDirect Topics

Lead sulfide is reconverted to pluite by heating the alkaline solution to 150–175 F and blowing with air, which converts sulfide to pluite. Lead sulfide itself was also used as sweetening agent. 2 The overall reaction is same as that given by the Doctor solution.
