Q. If NO_{2}(N_{2}O_{4}) is dissolved in NaOH, we get solution of ?
A) NaNO_{2}
B) NaNO_{3}
C) Mixture of NaNO_{2} and NaNO_{3}
D) NaNO_{4}
Explanation
(c)
Nitrogen dioxide ($NO_{2}$) exists as a dimer N_{2}O_{4.}
When it is dissolved in sodium hydroxide or any other alkali, a mixture of nitrate and nitrite is obtained.
2NO_{2}+2NaOH⟶NaNO_{2}+NaNO_{3}+H_{2}O
Sodium Sodium
nitrate nitrate
