Answer 1

1. HNO3 is a stronger acid than HNO2 is true.

Step-by-step explanation:

HNO3 has a stronger tendency to disassociate into H+ ions than HNO2.

The reverse is true of the other 2 pairs.

Answer 2

`HNO_3` is stronger than
`HNO_2`

Step-by-step explanation:

• In the given statements the option (i) is correct.

`HNO_3` is stronger than
`HNO_2`

• 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.
