Lead(II) acetate (Pb(CH3COO)2), also known as lead acetate, lead diacetate, plumbous acetate, sugar of lead, lead sugar, salt of Saturn, and Goulard's powder, is a white crystalline chemical compound with a sweetish taste. It is made by treating lead(II) oxide with acetic acid. Like other lead compounds, it is toxic. Lead acetate is soluble in water and glycerin. With water it forms the trihydrate, Pb(CH3COO)2·3H2O, a colourless or white efflorescent monoclinic crystalline substance. The substance is used as a reagent to make other lead compounds and as a fixative for some dyes. In low concentrations, it is the principal active ingredient in progressive types of hair colouring dyes. Lead(II) acetate is also used as a mordant in textile printing and dyeing, as a drier in paints and varnishes, and in preparing other lead compounds. It was historically used as a sweetener and for cosmetics. ==Production== Lead acetate can be made by boiling elemental lead in acetic acid and hydrogen peroxide. This method of using acetic acid and hydrogen peroxide will also work with lead carbonate or lead oxide. Pb(s) + H2O2 + 2 H+(aq) → Pb2+(aq) + 2 H2O(l) Pb2+ + 2 CH3COO−(aq) → Pb(CH3COO)2 Lead acetate can also be made via a single displacement reaction between copper acetate and lead metal: Cu(CH3COO)2 + Pb → Cu + Pb(CH3COO)2 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Lead(II) acetate」の詳細全文を読む スポンサード リンク
