Magnesium Sulfate and Magnesium Sulfate water containing no difference

    Magnesium sulfate, or magnesium sulfate heptahydrate, also known as Epsom, bitter salt, purging and salt, Epsom salt is a compound containing magnesium. Magnesium sulfate heptahydrate in air (dry) easily weathered into powder, heated gradually remove water of crystallization of anhydrous magnesium sulfate, molecular formula for MgSO4 (or MgSO4 7H2O), magnesium sulfate is a kind of chemical raw materials. Anhydrous magnesium sulfate is a commonly used chemical reagent and dry reagent. But magnesium sulfate often refers to seven water magnesium sulfate, because it is not easy to dissolve than anhydrous magnesium sulfate are more likely to weigh, to facilitate quantitative in industrial control.
