What is Lead Acetate?
Lead Acetate is also known as lead(II) acetate is a white crystalline chemical compound with the formula Pb(C2H3O2)2. It is poisonous in nature. It is used in making white lead in medicines and as a mordant in dyeing. Lead acetate was first produced in the United States in 1944. Lead belong to the group IV elements and most of the compounds have +2 state. Lead acetate is stable under ordinary conditions of use and storage. Lead acetate, also known as sugar of lead, is a white crystal made by the action of acetic acid on litharge. Lead acetate is used in gold toning baths to modify the pH.
Other names – Lead diacetate, Lead(II) acetate
