Tin(II) acetate is the acetate salt of tin(II), with the chemical formula of Sn(CH3COO)2. It was first discovered in 1822.
Preparation
To obtain tin(II) acetate, tin(II) oxide is dissolved in glacial acetic acid and refluxed to obtain yellow Sn(CH3COO)2·2CH3COOH when cooled. The acetic acid can be removed by heating under reduced pressure, and the white Sn(CH3COO)2 crystals can be obtained by sublimation.
Properties
Sn(CH3COO)2·2CH3COOH undergoes disproportionation and decomposition when heated under normal pressure, and products such as tin(IV) oxide and hydrogen are generated. The decomposition of anhydrous Sn(CH3COO)2 is to the blue-black tin(II) oxide.
Anhydrous Sn(CH3COO)2 decomposes in water, but complexes such as KSn(CH3COO2)3 and Ba2 can be formed in alkali metal or alkaline earth metal acetates.
