Ferrous Sulphate Heptahydrate
Ferrous Sulfate is a greenish, yellow-brown or white, odorless, crystalline (sand-like) powder. It is used in water treatment and in making other Iron compounds, and as a fertilizer and food additive.
Ferrous metals are hard, heavy, have high density, fragile, not malleable, ductile, magnetic, and rust. Non-ferrous metals are light, malleable, not magnetic, and more expensive. There are different ferrous metals, and each one has its uses. For example, steel is used in buildings, skyscrapers, and structures.
