What is Iron(II) sulfate?
Iron(2+) sulfate (anhydrous) is a compound of iron and sulfate in which the ratio of iron(2+) to sulfate ions is 1:1. Various hydrates occur naturally - most commonly the heptahydrate, which loses water to form the tetrahydrate at 57C and the monohydrate at 65C. It has a role as a reducing agent. It is an iron molecular entity and a metal sulfate. It contains an iron(2+).
