Description
Ferrous sulphate, also known as iron(II) sulphate, is a chemical compound composed of ferrous ions (iron(II)) and sulphate ions. It is typically found in hydrated forms, including ferrous sulphate monohydrate (FeSO4·H2O) and ferrous sulphate heptahydrate (FeSO4·7H2O), which are greenish-blue crystals. Ferrous sulphate is commonly used in various industrial and laboratory applications. It serves as a source of iron in the production of iron supplements and fertilizers. It is also used as a reducing agent, colorant in dyes and pigments, and as a mordant in textile dyeing. Additionally, ferrous sulphate has applications in water treatment, wastewater purification, and as a reagent in chemical synthesis.
