[tex]HNO_3[/tex] is stronger than [tex]HNO_2[/tex]
Explanation:
In the given statements the option (i) is correct.
[tex]HNO_3[/tex] is stronger than [tex]HNO_2[/tex]
In oxyacids, the acids having a number of atoms of more in number are stronger than the lower number of oxygen atoms.
The partial positive character on hydrogen atom increases with an increase in a number of oxygen atoms as the oxygen atom increases the overall electronegativity.
