Ferrous sulfate heptahydrate CAS: 13463-43-9
Ferrous Sulphate Hephydrate: Ntsuab vitriol, FeSO4.7H20, tau paub txij li xyoo pua kaum peb; nws crystallizes los ntawm kev daws cov hlau los yog hlau hauv paus hauv dilute sulfuric acid. Cov heptahydrate tsim ntsuab monoclinic crystals ntawm qhov ntom ntom 1·88, soluble hauv dej heev (296 g litre-1 FeS04 ntawm 25 ° C). Los ntawm precipitating aqueous tov nrog ethanol, cua sov lub heptahydrate rau 140 ° nyob rau hauv vacuo los yog crystallizing nws los ntawm 50% sulfuric acid, cov dawb monohydrate yog tau. Qhov no tuaj yeem ua rau lub cev qhuav dej ntxiv rau cov dawb, amorphous FeSO4 los ntawm cua sov rau 300 ° hauv ib qho tam sim no ntawm hydrogen. Thaum tshav kub kub cov sulphate decomposes: 2FeS04 -> Fe203 + S02 + S03 A tetrahydrate, FeS04.4H20, crystallizes los ntawm aqueous daws saum 56 °.
