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?

oleum


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.


What is the name of sulfuric 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 compound name of sulfuric 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.


How oleUm Made in contact Process?

By dissolving Sulfur trioxide in concentrated Sulfuric acid


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.


What is the structure 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


Is the chemical formula form sulfuric acid is H2SO4?

Yes. H2SO4 is sulfuric acid.


Weight of gallon of oleum sulfuric acid?

Oleum usually weight twice the water, density in SI varies between 1.9 - 2.0 kg/L. For Imperial unit it is approximately 16 Pound/Gallon. I suggest to verify concentration of Oleum for the exact density.


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.


Is triprotic acid a sulfuric acid?

Sulfuric acid gives away two protons to form the sulfate ion. Therefore it is a diprotic acid.


Acid rain can form when what in the air mixes with sulfur oxides to form sulfuric acid?

Acid rain forms when oxygen and nitrogen in the air mixes with sulfur oxides to form sulfuric acid, and that is the result

Sources of sulfuric acids?

Sulfuric acid (sulphuric in the UK) is obtained from sulfur (sulphur in the UK), a yellow mineral found in large quantities in volcanic regions. First the sulfur is melted and burned to form sulfur dioxide gas. This is passed with further oxygen over a catalyst of Vanadium oxide to speed up the reaction whereby a gas called sulfur trioxide is formed. Sulfur trioxide will react directly with water to produce sulfuric acid but as the reaction is so violent, the sulfur trioxide is dissolved first in some already made sulphuric acid. The resulting oily, fuming, corrosive liquid is called 'fuming sulfuric acid' or 'oleum'. This oleum is then reacted with water to form a double quantity of sulfuric acid, one lot being product required and the other sent back to the stage in the process where the sulfur trioxide is re-dissolved in it.


Can two liquids be mixed to form a solution?

Yes, water and concentrated sulfuric acid can be mixed together to form dilute sulfuric acid solution.


Can sulfur form sulfuric acid?

Yes. Burning sulfur in air will produce sulfur dioxide, which can then react with water to form sulfuric acid.


Sulfuric acid behavior with acid-base?

Sulfuric acid is considered to be a strong acid. It reacts with bases and alkali to form salts, specifically sulfates and hydrogen sulfates.
