Ferrous Sulphate
Ferrous Sulphate
Inorganic Chemical Compound
Ferrous sulphate is an inorganic chemical compound with the formula FeSO₄. It commonly appears as pale green crystals in its hydrated form and is readily soluble in water. The compound is mildly acidic and is known for its reducing properties.
It is commercially produced by dissolving iron in sulfuric acid. Ferrous sulphate is widely used in water treatment, fertilizers, pharmaceuticals, pigments, and as a source of iron in various industrial applications.

Ferrous Sulphate Applications
Ferrous sulphate is widely used as a micronutrient in fertilizers to correct iron deficiencies in soils and plants, promoting healthy growth and increased crop yield
Ferrous sulphate is employed in industrial processes such as the manufacturing of iron-based chemicals, pigments, and ferric compounds.
It is used as a mordant in textile dyeing and as a tanning agent in leather processing, improving color fastness and quality.
Ferrous sulphate is used in the pharmaceutical industry as an iron supplement to treat anemia and iron deficiency in humans and animals.
Ferrous sulphate is used in construction to remove undesirable compounds from cement and as a component in certain building material treatments.
It is used to improve acidic and alkaline soils by balancing soil pH and providing essential nutrients for plant development.
It is applied to control odor, reduce phosphorus in water bodies, and prevent algal blooms, contributing to environmental management.
In water and wastewater treatment, ferrous sulphate acts as a coagulant and flocculant, removing impurities, suspended solids, and phosphates, improving water clarity and quality.
