Question

Q8) Write the structure of Sulphuric acid and pyrosulphuric acid.
​

Answer 1

The chemical formula of sulfuric acid is H2SO4 and its molecular weight is 98.079 g/mol.The sulfur atom is bound to two oxygen atoms through double bonds, and two hydroxyl groups (OH) through single bonds. It is a diprotic acid, as it can release two protons.

Pyrophosphoric acid, also known as diphosphoric acid, is the inorganic compound with the formula H4P2O7 or, more descriptively, [(HO)2P(O)]2O. Colorless and odorless, it is soluble in water, diethyl ether, and ethyl alcohol. The anhydrous acid crystallizes in two polymorphs, which melt at 54.3 °C and 71.5 °C.
