Answer 1

ANSWER

Disulphurous acid or pyrosulphurous acid is an oxoacid of sulphur with the formula $H_2S_2O_5H .$

The salts of disulphurous acid are called disulphites or metabisulphites. The oxidation state of the sulfur atom bonded to 3 oxygen atoms is +5 while the oxidation number of other sulfur atom is +3.
