Question

$nitrogentrioxide\stackrel{hydrolysis}{\to }P$
Oxidation state of nitrogen in P is .

• A. 3
• B. 2
• C. 5

Answer 1

The correct option is A 3

$N_2{O}_3\stackrel{\mathrm{hydrolsis}}{\to }{\mathrm{HNO2}}^{}$

• $O^{2-}$ and $H^{+}$ are the oxidation states we see in the oxide of nitogen. On solving, we get oxidation state of nitogen to be +3.
