Chemical Information
FooDB NameMagnesium sulfate heptahydrate
DescriptionMagnesium sulfate heptahydrate, also known as mgso4.7H2O or conclyte-MG, belongs to the class of inorganic compounds known as alkaline earth metal sulfates. These are inorganic compounds in which the largest oxoanion is sulfate, and in which the heaviest atom not in an oxoanion is an alkaline earth metal. Magnesium sulfate heptahydrate is an extremely strong acidic compound (based on its pKa). Magnesium sulfate heptahydrate is a bitter tasting compound.
