Pyrosulfuric Acid Formula

Pyrosulfuric acid formula 

Pyrosulfuric acid has the formula H₂S₂O₇. The strong acid pyrosulfuric acid can be used to fume sulfuric acid. It is a Sulfur oxoacid. It’s made by combining Sulfur trioxide and sulfuric acid. It’s not as strong as sulfuric acid. Disulfuric acid is the name given to it. Because of its oily consistency and crystalline hue, it is also known as Oleum.
