Description
A white, crystalline solid that is made by the action of Acetic acid on Lead plates. Lead acetate is highly poisonous. Fresh lead acetate is soluble in water, but with exposure to air, lead acetate absorbs Carbon dioxide, thus changing into basic lead carbonate which is incompletely insoluble in water. Lead acetate was a common Drier added to oil paints an varnishes. It has also been used as a Mordant for dyes on Cotton, for weighting Silk and for making some lead-chrome pigments. Indicating papers can be made with lead acetate that are sensitive to vapor phase Hydrogen sulfide (Waller et al 2000).
