What is oxidation number of sulphur in SO ₃ ?
Options
- A+3
- B+4
- C+6
- D-3
Correct answer
C. +6
Step-by-step solution
Oxidation number of sulfur in SO ₃ In neutral compounds, the sum of oxidation numbers must equal zero, and oxygen typically has an oxidation number of -2 . Let the oxidation number of sulfur be x . For SO ₃ : x + 3 (-2) = 0 x - 6 = 0 x = +6 The oxidation number of sulfur in SO ₃ is +6 . The correct option is C.
