Sulphuric Acid

Whatsapp Order

Sulphuric Acid is a dense, highly corrosive, and strong mineral acid widely used as a fundamental chemical reagent and industrial raw material. It serves as a key component in fertilizer production, chemical synthesis, petroleum refining, and many other industrial processes. The 98% concentration is the concentrated, nearly pure form commonly utilized for manufacturing and processing applications demanding high acid strength and purity.
