Sulfuric acid (95–97%) is a highly concentrated, colorless to slightly yellow liquid classified as a strong mineral acid. Widely regarded as one of the most important industrial chemicals globally, it serves as a cornerstone for numerous manufacturing processes and laboratory applications. Its primary utility lies in its ability to act as a powerful dehydrating agent, a potent catalyst, and an effective reactant in chemical synthesis.
In the industrial sector, this concentration is predominantly utilized in the production of fertilizers, particularly superphosphates and ammonium sulfate, which are critical for global agriculture. It is also extensively employed in the refining of petroleum to remove impurities and in the manufacture of detergents, dyes, and synthetic fibers such as rayon. In metallurgy, it aids in the pickling of steel to remove rust and scale before further processing. Furthermore, due to its high affinity for water, it is frequently used as a drying agent for gases and organic solvents in laboratory settings where extreme dehydration is required.
Handling 95–97% sulfuric acid demands rigorous safety protocols due to its extreme corrosivity and reactivity. Upon contact with skin or eyes, it causes severe, deep tissue burns that can lead to permanent damage. A critical hazard is the intense exothermic reaction that occurs when it is mixed with water; adding water to the acid can cause violent boiling and splashing of hot, corrosive liquid. Therefore, the golden rule of dilution must always be followed: "Add acid to water," never the reverse. The vapor generated during handling can irritate the respiratory tract, necessitating the use of appropriate personal protective equipment (PPE), including acid-resistant gloves, face shields, and lab coats, within well-ventilated areas or fume hoods. Storage requires compatible materials like glass-lined steel or specific plastics, kept away from incompatible substances such as oxidizers, bases, and flammable organics. Proper disposal procedures must adhere strictly to local environmental regulations to prevent ecological contamination.
