Comparative Analysis of Ferrous Sulfate, Zinc Sulfate, and Copper Sulfate

Sulfate salts are a widely used class of chemical compounds in many industries. Three common examples are ferrous sulfate (FeSO₄), zinc sulfate (ZnSO₄), and copper sulfate (CuSO₄). Despite having the same anionic part (SO₄²⁻), these compounds differ significantly in chemical properties, appearance, and applications. This article will compare ferrous sulfate, zinc sulfate, and copper sulfate to help clarify their differences and support industrial decision-making.
