For 10 points, name this acid with formula H2SO4.
This compound protonates nitric acid in the precursor step to the nitration of benzene. Sodium nitrate is reacted with this compound in one method of producing it which uses Glover towers known as the lead chamber process, while another method uses a vanadium oxide catalyst and is called the (*) contact process. The "fuming" form of this strong diprotic acid is known as oleum. This compound is reformed during the recharging of lead acid batteries, and the reaction of sulfur trioxide with water forms this compound, leading to its presence in the atmosphere of Venus and acid rain.
