Question

What is sulphurs oxidation number in caro's acid?

Answer 1

Similarly 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.

Answer 2

Similarly Caro's acid Marshall's acid also has peroxide linkages so that in which She shows +6oxidation state or 2+2x-2=0 or x =+6.This cannot be true as maximum O. N. of Cr cannot be more than+6
