Question

O.S of sulphur in sulphurous acid, sulphuric acid, caros acid, oleum, marshals acid​

Answer 1

Answer:

H2SO4, two hydrogen has a charge of +2 and four oxygen has a charge of -8, the total charge of two hydrogen and four oxygen has (2 – 8 = -6) -6 charge so sulfur has a charge of +6 to “stable”

Sulfurous acid H2SO3 +4

Caro's acid, Marshall's acid also has a peroxide linkage so that in which S shows +6 oxidation state. or 2 + 2x – 12 – 2 = 0 or x = + 6. This cannot be true as maximum O. N. of Cr cannot be more than + 6. ... This exceptional value is due to the fact that four oxygen atoms in CrO5 are in peroxide linkage.
