Options
- A. +6 , +4
- B. +4, +6
- C. +4, +3
- D. +3, +4
Answer
B. +4, +6
Step-by-step solution
Let the oxidation number of Sulphur in SO _2 be x. x + 2(-2) = 0 x = +4 Let the oxidation number of Sulphur in SO _4^ 2- be y. y + 4(-2) = -2 y - 8 = -2 y = +6 The oxidation numbers of Sulphur in SO _2 and SO _4^ 2- are +4 and +6 respectively. Answer: +4, +6
