Sulfuric+acid

Sulfuric acid's molecular formula is H 2 SO 4. It is a colorless to a light yellow corrosive acid.


 * Sulfuric acid is a common type of acid
 * Acid rain has sulfuric acid in it which harms plants, fish, and other living things
 * It is used in car batteries and some drain cleaners
 * Human make more than 100 million tons of sulfuric acid per year
 * Sulfuric acid is a colorless, orderless, viscous liquid

Sulfuric acid is highly corrosive and is a very strong mineral acid. Its historical name is "oil of vitriol". The study of vitriol started during the ancient times when Sumerians listed the various vitriols based on their color. The historic name "oil of vitriol" was given by medieval European alchemists. Sulfuric acid is is either colorless or has a slight yellow tinit. It is soluble in water. It has a strong dehydrating property and if it is highly concentrated then it has a strong oxidizing property. Sulfuric acid is used in lead-acid batteries for cars and other vehicles. It can be used in mineral processing, fertilizer manufacturing, chemical synthesis, wastewater processing, and oil refining. Nearly 99% sulfuric acid can be made although the 98% grade is more stable in storage. When used in lead-acid batteries, the molarity of sulfuric acid is 4.2-5 mol/L with a density of 1.25-1.28 kg/L and a mass fraction of 29-32%. Acid produced in lead chamber is referred to as "Chamber acid" and acid retained from the bottom of the Glover tower is referred to as "Tower acid". They are considered commercial concentrations although they each can be prepared in the lab if needed.

Sulfuric acid's most common use is in the fertilizer making process. It is also used in petroleum refining to wash impurities out of gasoline and other refinery products. Sulfuric acid is also used in processing metals.

Iron and steel making factories use cleaning agents with sulfuric acid because it removes oxidation preventing rust from forming. Also sulfuric acid is a hygroscopic, therefore it is used as a drying agent as well.
 * Uses for Sulfuric Acid (Alternatively called sulphuric acid):**

=Safety= Sulfuric acid is highly corrosive and can cause very severe chemical burn upon contact as it decomposes proteins and lipids via amide hydrolysis and ester hydrolysis, like what other caustic acids and alkalis do. Yet, the corrosive property of sulfuric acid is also accentuated by its highly exothermic reaction with water (i.e. its dehydrating property) in which it can dehydrate the carbohydrates in organisms’ tissues liberating heat and posing secondary thermal burn. Due to such reasons, damage caused by sulfuric acid is potentially more serious than those of other comparable strong acids (e.g. hydrochloric acid, nitric acid). Moreover, sulfuric acid at a high concentration is a strong oxidizing agent which should be stored carefully.
