"Reaction Formula of Lead Acetate and Hydrogen Sulfide"

In a study, the reaction between lead acetate ($Pb (CH_ {3} COO) _ {2} $) and hydrogen sulfide ($H_ {2} S $) is studied. When the two meet, it becomes wonderful. The corresponding formula is: $Pb (CH_ {3} COO) _ {2} + H_ {2} S = PbS\ downarrow + 2CH_ {3} COOH $.

In this case, lead acetate combined with hydrogen sulfide, lead sulfide ($PbS $) precipitated, and acetic acid ($CH_ {3} COOH $) formed. Lead sulfide is black in color, so it can be seen that blackness sinks in the liquid, which is a significant sign of this.

This should, in the field of chemical, can test the existence of hydrogen sulfide. Because of its special appearance, it makes it important for facets such as evolution. Scholars study this should, clarify the rules of chemical application, and also increase the understanding of chemical application.
