|Section2= |Section7= |Section8= }} Sodium percarbonate is a chemical, an adduct of sodium carbonate and hydrogen peroxide (a perhydrate), with formula 2Na2CO3 · 3H2O2. It is a colorless, crystalline, hygroscopic and water-soluble solid. It is used in some eco-friendly cleaning products and as a laboratory source of anhydrous hydrogen peroxide. This product contains the carbonate anion, and should not be confused with sodium peroxocarbonate Na2CO4 or peroxodicarbonate Na2C2O6, which contain different anions. Sodium percarbonate was first prepared in 1899 by Russian chemist Sebastian Moiseevich Tanatar (Севастьян Моисеевич Танатар) (7 October 1849, Odessa, Russia — 30 November 1917, Odessa, Russia).〔S. Tanatar (1899) ("Percarbonate," ) ''Berichte der Deutschen chemischen Gesellschaft zu Berlin'', 32 : 1544-1546.〕 ==Structure== At room temperature, solid sodium percarbonate has the orthorhombic crystal structure, with the ''Cmca'' crystallographic space group. The structure changes to ''Pbca'' as the crystals are cooled below about −30 °C.〔 〕 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「sodium percarbonate」の詳細全文を読む スポンサード リンク
