B

Pyrosulphuric acid

C

Dithionous acid

D

Thiosulphuric acid

Text Solution

Verified by Experts

The correct Answer is:
C
Dithinous acid `(H_(2) S_(2)O_(4))` has sulphur in `+3` oxidation state.
`HO - overset(O) overset(||)(S) - overset(O) overset(||)(S) - OH, 2(+1) + 2x + 4(-2) = 0` ltbrlt `2x = 8 - 2 = 6, x = +3`
