Sulfuric acid (oil of vitriol, H2S04) is a colorless, oily liquid, dense, highly reactive, and miscible with water in all proportions. Heat is evolved when concentrated sulfuric acid is mixed with water and, as a safety precaution, the acid should be poured into the water rather than water poured into the acid. Anhydrous, 100% sulfuric acid, is a colorless, odorless, heavy, oily liquid (boiling point 338°C with decomposition to 98.3% sulfuric acid and sulfur trioxide). Oleum is excess sulfur trioxide dissolved in sulfuric acid. For example, 20% oleum is a 20% sulfur trioxide-80% sulfuric acid mix. Sulfuric acid will dissolve most metals and the concentrated acid oxidizes, dehydrates, or sulfonates most organic compounds, sometimes causing charring. 

A second example illustrates the ability of transition metals to form complexes with small molecules and ions. Copper metal and hot concentrated sulfuric acid ( oil of vitriol ) react to form solid copper(II) sulfate, commonly called blue vitriol by virtue of its deep blue color. There is more to this compound than copper and sulfate, however it contains water as well. When the water is driven away by heating, the blue color vanishes, leaving greenish white anhydrous copper(II) sulfate (Fig. 8.11). The blue color of blue vitriol comes from a...

Pure sulfuric acid is a viscous clear liquid, like oil, and this explains the old name of the acid ( oil of vitriol ). 

In the days of alchemy and the phlogiston theory, no system of nomenclature that would be considered logical ia the 1990s was possible. Names were not based on composition, but on historical association, eg, Glauber s salt for sodium sulfate decahydrate and Epsom salt for magnesium sulfate physical characteristics, eg, spirit of wiae for ethanol, oil of vitriol for sulfuric acid, butter of antimony for antimony trichloride, Hver of sulfur for potassium sulfide, and cream of tartar for potassium hydrogen tartrate or physiological behavior, eg, caustic soda for sodium hydroxide. Some of these common or trivial names persist, especially ia the nonchemical Hterature. Such names were a necessity at the time they were iatroduced because the concept of molecular stmcture had not been developed, and even elemental composition was incomplete or iadeterminate for many substances. 

Sulfuric acid (H2S04) wins the prize for being the number one chemical produced worldwide. This acid is a colorless, odorless, thick liquid. The concentrated form of the acid is also called oleum, the Latin word for oil. In fact, it is so thick that it was once called oil of vitriol, a nickname given to the concentrated chemical because of its corrosiveness. 

The first industrial preparation of sulfuric add from green vitriol (ferrous sulfate), according to Hermann Kopp, was by Johann Christian Bernhardt in 1755 (9,10). A fuming sulfuric acid known as Nordhausen oil of vitriol was manufactured at Nordhausen, Thuringia, from partially dehydrated green vitriol (11). 

In 1771 G. W. Scheele investigated a green variety of fluorspar from Garpenberg and a white one from Gislof in Scania. He found that the green specimen contained a trace of iron but that the white one did not. When he heated the pulverized mineral with oil of vitriol [sulfuric acid], he noticed that the inner surface of the glass retort became corroded,...

Oil of vitriol was prepared by heating a natural vitriol, most typically green (iron) vitriol. This yielded sulfur trioxide which combined with the moisture of the air to give a fairly concentrated sulfuric acid. The name, oil of vitriol, was derived from its source, and from its viscous nature. Acid (or spirit) of sulfur was made by the combustion of common sulfur, the sulfur dioxide produced reacted with the moisture and the oxygen of the atmosphere to give a much more dilute solution of the same acid, mixed with some unoxidized sulfur dioxide.
