Epsom salts are otherwise known as: Magnesium sulfate heptahydrate MgSO4 7H2O but I can't seem to find a picture of the crystal structure anywhere... skermit-ga |

As regards the crystal structure, it is a polymorph! That means that the hepthydrate form of Magnesium sulphate can be an orthorhombic crystal with a 2,2,2 symmetry (it is disphenoidal, and that's rare). It also can be a monoclinic just like hydrated iron sulphate. For reference go to either of these pages. Images on the second one. http://www.es.ucl.ac.uk/research/planetaryweb/postgraduate/domweb/epsomite.htm http://www.galleries.com/minerals/sulfates/epsomite/epsomite.htm For some really cool close-ups, go here: http://www.oncloserinspection.com/Image_Galleries/Magnesium_Sulfate/mgso4.htm Alan Kali |
