Ammonium ferric sulfate Detailed introduction: is a lavender octahedral crystal or an off-white powder or an orthorhombic prismatic crystal flowing as a pale yellow powder. Sensitive to light. Easy to absorb moisture. Dissolved in water slowly, but in the water when there are trace amounts of ferrous sulfate dissolved quickly, slightly soluble in ethanol, almost insoluble in acetone and ethyl acetate. Slowly hydrolyzed in aqueous solution. Relative density (d18) 3.097. Heat to 480 ° C decomposition. The product usually contains about 20% water in light yellow. There are also 9 molecules of crystal water. Relative density 2.1.175 ℃ lost 7 molecules of crystal water.
