Melanterite (iron II sulfate) – Properties, Photos and Occurence
The Mohs hardness is only 2, density is 1.9. Melanterite has conchoidal fracture and displays cleavage in two directions. Beware, melanterite is highly soluble in water! Fresh bright green melanterite stalagmites and encrustations, note older partially dehydrated and oxidized melanterite with yellow and rusty parts.
Activity of water in aqueous ferrous sulfate solutions at 25 °C.,The H2O–FeSO4 system has been modelled using the Pitzer activity coefficient approach over a temperature interval of ?2–220 °C and in concentrations from pure water to the solubility limit …
Iron(II) sulfate – Sciencemadness Wiki
Infobox references. Iron (II) sulfate, also known as ferrous sulfate is the sulfate salt of the iron (II) ion. It is most commonly seen as the heptahydrate which forms blue-green crystals. It is a brownish-white powder when anhydrous. The old name for the iron (II) sulfate is green vitriol .
