说明

一般描述

Magnesium sulfate (Epsom Salt)[1] 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.[2] 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.[3]
