Physical and Chemical Properties | Lead acetate, also known as lead acetate, is a white crystalline compound, sweet, used to be called lead sugar. Like other lead compounds, lead acetate is also very toxic. Lead acetate is soluble in water or glycerol. And water to form a trihydrate, Pb(CH3COO)2 · 3H2O, is a colorless or white flower-like monoclinic crystal. Low concentrations of lead acetate are the main active ingredient in progressive hair dyeing products. |
