What percent oleum is sulfuric acid?
Oleum, also known as fuming sulfuric acid or pyrosulfuric acid, is a solution of sulfur trioxide (SO3) in concentrated sulfuric acid (H2SO4).
Traditional name for concentrated fuming sulfuric acid?
The traditional Latin name for fuming sulfuric acid is Oleum. It comes from the Latin word for oil (oleum). It is also called Nordhausen acid.
How oleUm Made in contact Process?
By dissolving Sulfur trioxide in concentrated Sulfuric acid
How is oleum made?
Oleum is typically produced by dissolving sulfur trioxide (SO3) in concentrated sulfuric acid (H2SO4).
Can ninety two percent sulfuric acid prepared by adding liquid SO3 to eighty four percent sulfuric acid?
Yes, BUT... Liquid SO3 is HIGHLY reactive and not readily available. Pure SO3 reacts readily (and violently) with water or sulfuric acid. To manufacture sulfuric acid, dilute gaseous SO3 is absorbed in sulfuric acid to increase the concentration of the acid. 100% sulfuric acid can still absorb more SO3. When extra SO3 is dissolved in 100% H2SO4 (sulfuric acid) the solution is called oleum or fuming sulfuric acid. In general, oleum is used when free SO3 is required.
Among sulfuric acid and oleum which is the strong acid?
Oleum is more stronger acid than Sulfuric acid
What percent oleum is sulfuric acid?
Oleum, also known as fuming sulfuric acid or pyrosulfuric acid, is a solution of sulfur trioxide (SO3) in concentrated sulfuric acid (H2SO4).
Traditional name for fuming sulfuric acid?
The traditional name for fuming sulfuric acid is Oleum. Oleum is used for in water based aerosol coatings. Rust-Oleum has the fuming sulfuric acid in its name and hold many patents on its usage.
What is the traditional name for concentrated fuming sulfuric acid?

What is the name of sulfurous acid?
"Sulfuric acid." If you're looking for an archaic name, "vitriol" or "oil of vitriol." If you are looking for the name of the Industrial concentrated form, it is "Oleum" which is Latin for oil.
What is the molecular formula of oleum?
Oleum or fuming sulfuric acid refers to a solution of various compositions of sulfur trioxide (SO3) in sulfuric acid (H2SO4), which can also be described by the formula H2SO4.xSO3 where x is defined as the molar free sulfur trioxide content.As being a mixture it does not have a chemical structural formula.

What is the Sulfonation process to produce dodecyl benzene sulfonic acid?
Dodycyle benzene is reacted with oleum or sulfuric acid in slow addition and strong agittation manner
Why is the sulfurtrioxide formed in step2 of contact process not made to react with water?
Because the reaction is extremely exothermic and can produce an acid mist, which is dangerous and difficult to condense. It dissolves more quietly in concentrated sulfuric acid to form oleum, which can be diluted.
