Sulfuric acid is a highly corrosive mineral acid with the chemical formula
.
It is one of the most widely produced chemicals in the world, often called the "King of Chemicals" because it is essential to so many industries.
Key Characteristics
Physical State: A colorless, odorless, and syrupy (oily) liquid.
Acidity: A strong mineral acid that is highly soluble in water.
Hygroscopy: It has a natural affinity for water, meaning it can absorb moisture from the air or even strip water molecules from organic materials (like sugar or wood), leaving carbon behind.
Common Uses
Agriculture: Over 60% of production goes into making fertilizers (like superphosphates and ammonium sulfate).
Automotive: It is the electrolyte used in lead-acid batteries for cars.
Industrial Cleaning: Used for "pickling" (removing rust and scale) from steel and iron before they are processed.
Chemical Synthesis: Crucial for making detergents, dyes, pigments (like titanium dioxide), and explosives.
Refining: Used in petroleum refining to remove impurities from gasoline.
Safety First!
The Golden Rule: When diluting, always add acid to water, never water to acid. Adding water to concentrated acid causes a violent exothermic reaction that can splash boiling acid onto you.
Corrosivity: It causes severe chemical burns upon contact with skin and can lead to permanent blindness if it gets in the eyes.
Protection: Always wear goggles, chemical-resistant gloves, and an apron when handling it.
