Pyrosulfuric acid is the main constituent of fuming sulfuric acid and is a strong acid and. It is also known as disulfuric acid or oleum which is an oxyacid of sulfur. Pyrosulfuric acid is weaker than sulfuric acid. Salts such as sodium and potassium pyrosulfates are obtained by reacting with the bases.
The property value of hydrogen bond donor and hydrogen bond acceptor is 2 and 7 respectively. The rotatable bound count is 7. The acid can be synthesised by reacting excess SO3 with sulfuric acid.
