HI FRIEND!! Sulphuric acid (British English: sulphuric acid), H2SO4, is a strong mineral acid. It is soluble in water at all concentrations. It was once known as oil of vitriol, coined by the 8th-century Alchemist Jabir ibn Hayyan, the chemical's probable discoverer[1]. Sulphuric acid has many applications, and is produced in greater amounts than any other chemical besides water. World production in 2001 was 165 million tonnes, with an approximate value of $8 billion. Principal uses include ore processing, fertilizer manufacturing, oil refining, waste water processing, and chemical synthesis. Many proteins are made of sulphur-containing amino acids (like cysteine and methionine) which produce sulphuric acid when metabolised by the body.

Physical properties
[edit] Forms of sulfuric acid
Although 100% sulfuric acid can be made, this loses SO3 at the boiling point to produce 98.3% acid. The 98% grade is also more stable for storage, making it the usual form for "concentrated" sulfuric acid. Other concentrations of sulfuric acid are used for different purposes. Some common concentrations are:
* 10%, dilute sulfuric acid for laboratory use (pH 1)
* 33.5%, battery acid (used in lead-acid batteries) (pH 0.5)
* 62.18%, chamber or fertilizer acid (pH about 0.4)
* 77.67%, tower or Glover acid (pH about 0.25)
* 98%, concentrated (pH about 0.1)
Since sulfuric acid is a strong acid, a 0.50 M solution of sulfuric acid has a pH close to zero.
Different purities are also available. Technical grade H2SO4 is impure and often colored, but it is suitable for making fertilizer. Pure grades such as US Pharmacopoeia (USP) grade are used for making pharmaceuticals and dyestuffs.
When high concentrations of SO3(g) are added to sulfuric acid, H2S2O7 forms. This is called pyrosulfuric acid, fuming sulfuric acid or oleum or, less commonly, Nordhausen acid. Concentrations of oleum are either expressed in terms of % SO3 (called % oleum) or as % H2SO4 (the amount made if H2O were added); common concentrations are 40% oleum (109% H2SO4) and 65% oleum (114.6% H2SO4). Pure H2S2O7 is in fact a solid, melting point 36 °C.

H2SO4 is either dilute or concentrated Sulphuric acid...it is one of the most important chemical acids in laboratoru and industrial preparations........it also has a great number of uses...

H2SO4 is sulphuric acid and it is the king of all acids ,coz it is the strongest acid among other organic acids.Conc.sulphuric acid is very dangerous and harmful to living and non living things. It is very useful for many chemical process. If used for harming purpose,it is a killer.
