The oxidation number of sulphur in H ₂ ~S ₂ O ₈ is
Options
- A+2
- B+6
- C+4
- D+7
Correct answer
B. +6
Step-by-step solution
20-atoms are in peroxide linkage Their oxidation state =-1 and, oxidation state of remaining 60 -atoms, =-2 Oxidation state of H -atoms =+1 Let oxidation state of S atom =x aligned & S ₂ H ₂ O ₆ O ₂ & 2 x+2(+1)+6(-2)+2(-1)=0 & 2 x+2-12-2=0 & x=+6 aligned
