Description :
Gray or light yellow powder, hygroscopic,
aqueous solution is acid reaction. Light sensitive. Dissolve in water slowly,
but in the water when trace ferrous sulfate solution quickly, slightly soluble
in ethanol, almost insoluble in acetone and ethyl acetate. In aqueous solution
hydrolysis slowly. Heat to 480 ℃ decomposition. Goods are usually about 20%
water is light yellow. With nine molecules of water of crystallization. 175 ℃
lost 7 molecular crystal water.
