Understanding Ferrous Sulfate Monohydrate: Uses, Benefits, and Applications

What is Ferrous Sulfate Monohydrate?

Ferrous sulfate monohydrate, often referred to as iron(II) sulfate or green vitriol, is an inorganic compound with the formula FeSO₄·H₂O. It is a pale green crystalline solid that is highly soluble in water. This compound is a key source of iron and is widely used in various industries due to its unique properties.

Chemical Composition and Properties

Ferrous sulfate monohydrate consists of one molecule of water (H₂O) for each molecule of ferrous sulfate (FeSO₄). This hydration gives it its monohydrate classification. The compound has a molar mass of approximately 169.91 g/mol and is often encountered in its hydrated form. It is important to note that ferrous sulfate is distinct from ferric sulfate (Fe₂(SO₄)₃), which contains iron in a higher oxidation state.

Key Properties:
– Appearance: Pale green crystals or powder
– Solubility: Highly soluble in water
– Stability: Stable under normal conditions, but can oxidize to ferric sulfate when exposed to air
