Difference between fuming sulfuric acid and sulfuric acid?
Fuming sulfuric acid is sulfuric acid that contains added sulfur trioxide,so3.
Actually, fuming sulfuric acid is a one state of sulfuric acid. It is the concentrated sulfuric acid. It contains sulfuric acid 98% w/w.
It depends a little on your definition. Concentrated Sulfuric Acid can be produced up to 98% or 98.3% pure H2SO4. So, while H2SO4 would be considered a compound, it is never pure, and is always found in a mixture. Most Sulfuric Acid used in the lab is a much more dilute mixture of Sulfuric Acid and Water. Fuming Sulfuric Acid is a mixture between Sulfuric Acid, H2SO4 and sulfur trioxide SO3.
The strongest of acids are called fuming acids or anhydrous acids. Fuming nitric and fuming sulfuric acids are so strong that adding water to them converts them to nitric and sulfuric acids generating a very great amount of heat. Anhydrous acetic acid is likewise so strong that adding water will convert it to 100% acetic acid. These 3 acids are used in special reactions in chemistry where only the strongest acids will do.
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…
In an aromatic sulfonation reaction, a sulfonyl group (-SO3H) replaces a hydrogen on an aromatic ring (such as benzene). This is done by refluxing (heating to boiling with a reflux condenser) the aromatic with fuming sulfuric acid (concentrated sulfuric acid with gaseous SO3 present). This reaction is reversible, so mixing the aryl sulfonic acid with a dilute acid will reform the sulfuric acid and remove the sulfonyl group from the arene.
If you used hydrochloric acid and metal would the reaction have been the same if you had used sulfuric?
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.
A strong acid is and acid that completely dissociates (breaks apart into ions) in water. Whether an acid is strong or weak depends on the specific acid (i.e. sulfuric acid is strong, acetic acid is weak etc.). A concentrated acid is and acid that is nearly pure, regardless of how strong it is. For example both 95% acetic acid and 95% sulfuric acid would be considered concentrated, even though sulfuric acid is strong while acetic…
Sulfate is the ion SO42- and sulfuric acid is that ion plus two hydrogens: H2SO4. Sulfate ion can be associated with any number of positively charged ions, and is never found alone because of it's negative charge. Sulfuric acid is molecule that is a strong acid because when added to water, hydrogen ions are released into water making it acid.
Sulphur and sulfur are alternate spellings. Sulphur is more popular in Great Britain. It's similar to the difference between Colour and Color, except that sulphur is clearly and unambiguously wrong, as determined by IUPAC. Not that IUPAC always gets it right... "aluminium" indeed... but at least they're definitive.
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…
