Chemical properties:
It is white or colorless needle-like or oblique columnar crystal, odorless, cool and slightly bitter, molecular weight: 246.47, specific gravity 1.68, soluble in water, slightly soluble in ethanol and glycerin, soluble in its own crystal water at 67.5 °C. Decomposed by heat, 70, 80 ° C is the loss of four molecules of crystal water. At the 200 ° C of the month, all the crystal water was lost to an anhydrate. It is easily weathered into powder in air (dry), and gradually removes crystal water into anhydrous magnesium sulfate when heated. This product does not contain any toxic impurities. Magnesium sulfate heptahydrate is easier to weigh than anhydrous magnesium sulfate because it is not easily dissolved, which facilitates quantitative control in the industry.
Classification: 
Magnesium sulfate often refers to magnesium sulfate heptahydrate (because it is not easy to dissolve, it is easier to weigh than anhydrous magnesium sulfate, which is convenient for quantitative control in industry.) There are also water, dihydrate, trihydrate, and anhydrous. Magnesium sulfate.
Magnesium sulfate heptahydrate has industrial grade and feed grade, granular, according to the size of 0.1-1mm, 1-3mm, 2-4mm three.
Others such as anhydrous, monohydrate, dihydrate, and magnesium sulfate trihydrate are in powder form.
