What is the oxidation number of S in H ₂ ~S ₂ O ₈ ?

Options

  1. A+5
  2. B+4
  3. C+7
  4. D+6

Correct answer

D. +6

Step-by-step solution

The structure of H ₂ ~S ₂ O ₈ is as follows Let the oxidation state of sulphur be x . Then, 2 x+2+2(-1)+6(-2)=0 x=+6 Thus, the oxidation state of S in H ₂ ~S ₂ O ₈ is +6 .
