General description
Magnesium sulfate (Epsom Salt) is an inorganic salt. Quantitative determination of the solubility of manganese sulfate monohydrate in the presence of a co-salt of magnesium has been studied. Raman spectra of 10 hydrated and anhydrous forms of magnesium sulfates have been reported. Their crystal structure and space groups have been evaluated by Raman and XRD (X-ray diffraction) studies.
