From a chemical perspective, ferrous sulfate is a soluble compound that can dissolve in water but not in ethanol. It has a white powder appearance and no odor, making it safe and easy to handle. However, ferrous sulfate can be weathered in dry air and oxidized into brown basic ferric sulfate on the surface in humid air. It becomes tetrahydrate at 56.6℃ and monohydrate at 65℃. Nevertheless, its properties still make it a valuable ingredient in many industrial processes.
One of the primary uses of ferrous sulfate is to make iron salt, which is an essential nutrient for humans and animals. Iron is required for the formation of hemoglobin, a protein that transports oxygen in the bloodstream. Thus, ferrous sulfate is often added to food and dietary supplements to prevent iron deficiency and anemia. In addition, ferrous sulfate is used to make iron oxide pigment, which is a colorant for paints, coatings, and plastics.
Besides its role in iron chemistry, ferrous sulfate is known for its ability to act as a mordant, which is a substance that helps fix dyes to fabrics or other materials. This property makes ferrous sulfate a useful additive in textile printing and dyeing. It can also be used as a water purifier, antiseptic, and disinfectant due to its antimicrobial properties. Ferrous sulfate is effective against a wide range of pathogens, including bacteria, viruses, and fungi.
