The oxidation number of nitrogen atoms in NH ₄ NO ₃ are
Options
- A+5 , +5
- B-3,+5
- C+3,-5
- D-3,-3
Correct answer
B. -3,+5
Step-by-step solution
NH ₄ NO ₃ NH ₄⁺+ NO ₃⁻ (N₁ ) (N₂ ) For oxidation number of N₁ x+4=+1x=+1-4=-3 So, oxidation state of first nitrogen is -3 . For oxidation state of second nitrogen (N₂ ) aligned x-6 &=-1 x &=-1+6=+5 aligned So, the answer is -3 and +5 .
