Question

No3- oxidation numbers

Answer 1

Oxidation number of N in NO₃⁻ = +5

Oxidation number of O in NO₃⁻ = -2

Please mark me brainliest

Answer 2

Let the oxidation no. of N in NO³- be 'X'....

The oxidation state of oxygen is –2....

Since,, the atom as whole is single negatively charged ,, following eq. hold this true:-

➡ X + 3 × (–2) = –1

➡ X – 6 = –1

➡ X = +6 –1

➡ X = 5

Therefore,, the no is 5

✳ Oxidation no of O in NO³- is :- –2 ..

I hope it will be helpful✌✌✌
