Dithionic acid is `H_(2)S_(2)O_(6)`:
`HO-underset(O)underset(||)overset(O)overset(||)(S)-underset(O)underset(||)overset(O)overset(||)(S)-OH`
Sulphurous acid is `H_(2)SO_(3)`:

Pyrosulphuric acid (oleum) is `H_(2)S_(2)O_(7)`:
`HO-underset(O)underset(||)overset(O)overset(||)(S)-O-underset(O)underset(||)overset(O)overset(||)(S)-OH`
