Ferric Sulphate (Fe₂(SO₄)₃·xH₂O) is an inorganic compound widely used as a coagulant, flocculant, and oxidizing agent. It exists in both anhydrous and hydrated forms, with the hydrated form being more common due to its stability and ease of handling. Ferric sulphate is a yellowish-brown crystalline solid or powder that is highly soluble in water, forming a strongly acidic solution. It plays a critical role in water treatment, industrial processes, and environmental applications.
