Versuchsvorschrift

The results described above would not have been expected because sodium sulfate absorbs more water per unit weight than magnesium sulfate. One kilogram of sodium sulfate (7.04 moles) absorbs 70.4 moles of water to form sodium sulfate decahydrate, or 1.27 kg water/kg sodium sulfate. One kilogram of magnesium sulfate (8.31 moles) absorbs 58.15 moles of water to form magnesium sulfate heptahydrate, or only 1.05 kg water/kg magnesium sulfate. Therefore, there would have been no reason to expect aqueous biocide compositions to form solids with much smaller amounts of magnesium sulfate, relative to sodium sulfate.
