Question

Sum of oxidation state of nitrogen atom in hyponitrous acid, nitric acid and nitrous acid.
​

Answer 1

Answer:

The oxidation numbers of hydrogen and oxygen are +1 and -2 respectively. In a neutral molecule, the sum of the oxidation numbers of all the elements is zero. Calculate the oxidation number of nitrogen atoms in nitric acid. Hence, the oxidation number of nitrogen atoms in nitrous acid is +3

Answer 2

Answer:

Explanation:

N  2 (OH)  2

​

 

                2x+2(−1)=0

                   2x=2

                   x=+1

Nitric acid,

HNO2

 

​

 

                   1+x+3(−2)=0

                    x=+5

Nitrous acid,

HNO  

2

​

 

                    1+x+2(−2)=0

                     x=+3

Sum of the oxidation state of the nitrogen atom in hyponitrous acid, nitric acid and nitrous acid is 1+5+3=9.
