Question

$HN{O}_2$ acts both as reductant and oxidant, while $HN{O}_3$ acts only as oxidant. It is due to their

• A. Solubility ability
• B. Maximum oxidation number
• C. Minimum oxidation number
• D. Minimum number of valence electrons

Answer 1

The correct option is B Maximum oxidation number

Solution: Correct option is b).
n $H\stackrel{\ast }{N}{O}_2$ oxidation number of $N=+3$
In $H\stackrel{\ast }{N}{O}_3$ oxidation number of$N=+5$.
