The difference between magnesium

The most obvious difference between magnesium sulfate monohydrate and magnesium sulfate heptahydrate is the appearance. Magnesium monohydrate is a white powder solid, while magnesium heptahydrate is a colorless and transparent crystal.


In terms of chemical structure, magnesium monohydrate is a hydrated magnesium sulfate containing one crystal water, with a relative molecular weight of 138, seven crystal water containing seven magnesium heptahydrate and a relative molecular weight of 246. Therefore, magnesium monohydrate and magnesium heptahydrate of the same quality, in which the percentage of magnesium element is 1.78 times of magnesium heptahydrate (therefore, in the agricultural production process, the effective magnesium component of magnesium monohydrate is higher than that of magnesium heptahydrate).
