Physical Properties

Sulfuric acid (alternative spelling sulphuric acid), also known as vitriol, is a mineral acid composed of the elements sulfur, oxygen and hydrogen, with molecular formula H2SO4. It is a colorless, odorless, and viscous liquid that is soluble in water and is synthesized in reactions that are highly exothermic.

Its corrosiveness can be mainly ascribed to its strong acidic nature, and, if at a high concentration, its dehydrating and oxidizing properties. It is also hygroscopic, readily absorbing water vapor from the air.Upon contact, sulfuric acid can cause severe chemical burns and even secondary thermal burns; it is very dangerous even at lower concentrations.

Sulfuric Acid concentrations are used for different purposes. Some common concentrations are:

Mass fraction H2SO4	Density (kg/L)	Concentration (mol/L)	Common name
<29%	1.00-1.25	<4.2	diluted sulfuric acid
29-32%	1.25-1.28	4.2-5.0	battery acid (used in lead-acid batteries)
62-70%	1.52-1.60	9.6-11.5	chamber acid fertilizer acid
78-80%	1.70-1.73	13.5-14.0	tower acid Glover acid
98.3%	1.84	18.4	concentrated sulfuric acid

Applications of Sulfuric Acid

1.sulfuric acid is used in produce fertilizers, particularly superphosphates, ammonium phosphate and ammonium sulfates.

2.sulfuric acid is used in chemical industry for production of detergents, synthetic resins, dyestuffs, pharmaceuticals, petroleum catalysts, insecticides and antifreeze, as well as in various processes such as oil well acidizing, aluminum reduction, paper sizing, water treatment.

3.sulfuric acid is used in pigments and include paints, enamels, printing inks, coated fabrics and paper.

4.sulfuric acid is also used in production of explosives, cellophane, acetate and viscose textiles, lubricants, non-ferrous metals, and batteries.

STORAGE

Store in a cool, dry, well-ventilated area away from combustible substances. Keep container tightly closed when not in use. Do not store near alkaline or organic substances. Store in a cool place away from heated areas, sparks and flame. Do not add any other material to the container.

Do not store in a damp atmosphere. Do not get in eyes, on skin or on clothing. Do not allow smoking and food consumption while handling. Handle in accordance with good storage and handling practices. Do not store near flammable substances. Wash thoroughly after handling.
