Ferrous Sulphate Monohydrate：Sulfate chemical FESO4, commonly, seven crystal water sulfate FESO4 · 7H2O, commonly known as green alum. Light blue -green monocular crystal, density of 1.898g/cm3, chemicalbook64 ℃ melted in crystalline water. Soluble in water, the aqueous solution is acidic. Gradually weathered in the air, and was oxidized into yellow -brown alkaline iron salt. Lost all crystal water at 300 ° C, and the waterless object is white powder.
Main nature: Iron sulfate is easily oxidized into yellow or iron rusty in wet air. In the water, the concentration of the solution for general sulfate is about 10 %. As a concrete, mixed with ChemicalBook Granules, good vegetables, fast sinking, very good coloring effects, low cost of sulfate treatment agents, and suitable for wastewater treatment with PH value above 8.5.
