Answer»

`H_(2)S_(2)O_(3)`
`H_(2)SO_(5)`
`H_(2)S_(2)O_(7)`
`H_(2)S_(4)O_(6)`

SOLUTION :`UNDERSET((50%))(2H_(2)SO_(4))+2H^(o+)+2HSO_(4)^(-) , 2HSO_(4)^(-) to H_(2)S_(2)O_(8)+2e^(-)`
`H_(2)S_(2)O_(8)+H_(2)O overset(F.D.)to H_(2)SO_(5) +H_(2)SO_(4), H_(2)SO_(5)+H_(2)Ooverset(F.D.)to H_(2)O_(2)+H_(2)SO_(4)`
