Ferrous sulfate heptahydrate CAS: 13463-43-9

tlhaloso e khuts'oane:

Ferrous Sulphate Hephydrate: Green vitriol, FeSO4.7H20, e tsejoa ho tloha lekholong la leshome le metso e meraro la lilemo; e phatsima ho tsoa mothapong oa tšepe kapa tšepe ka ho hlapolla sulfuric acid. Heptahydrate e etsa likristale tse tala tsa monoclinic tsa density 1 · 88, tse qhibilihang haholo metsing (296 g litre-1 FeS04 at 25 ° C). Ka precipitating tharollo aqueous ka ethanol, futhumatsang heptahydrate ho 140 ° ka vacuo kapa ka crystallizing ho tloha 50 % sulfuric acid e, e tšoeu monohydrate e fumanoa. Sena se ka felloa ke metsi ho feta ho FeSO4 e tšoeu, e amorphous ka ho futhumatsa ho 300 ° ka hona joale ea hydrogen. Ha mocheso o le khubelu sulphate e senyeha : 2FeS04 -> Fe203+S02+S03 A tetrahydrate, FeS04.4H20, e phatsima ho tsoa metsoakong ea metsi e ka holimo ho 56 °.
