It dissolves slowly in water, but dissolves quickly when there is a trace of ferrous sulfate in water, is slightly soluble in ethanol, and is almost insoluble in acetone and ethyl acetate. Slowly hydrolyze in aqueous solution. Relative density (d18) 3.097. Heat to 480 ° C decomposition. The product usually contains about 20% water in a pale yellow color. There are also 9 molecules of crystal water. Seven molecules of crystal water were lost at 175 °C.
