| copperas |
Iron(II) sulfate, also known as ferrous sulfate and as copperas (FeSO4) is an example of an ionic compound. It is found in various states of hydration (FeSO4·H2O, FeSO4·4H2O, FeSO4·5H2O, FeSO4·7H2O); the heptahydrate is also called green vitriol, copperas, or melanterite (a mineral that commonly occurs with pyrite). Iron(II) sulfate has a blue-green color, monoclinic crystal structure, and is water-soluble. Its molecular weight is 151.9026 g/mol. ...
